Click Fraud K9 Alternatives 2026: 7 Tools That Actually Work (K9 is Defunct)

Last updated: April 2026
The best ClickExpose alternatives in 2026 are ClickPatrol (best overall value for SMBs and mid-market, from EUR 59/mo with four protection modules and three-platform coverage), ClickCease (best for established detection with session recordings, from $63/mo), and Lunio (best for multi-platform coverage across 13+ ad networks). For GDPR-first analytics, Fraud0 stands out with 4,000+ data points and no cookies. ClickGuard offers the deepest per-campaign customization. TrafficGuard is best for mobile app and affiliate fraud. Budget-conscious advertisers should consider Fraud Blocker. Most advertisers looking beyond ClickExpose want broader platform coverage, stronger detection accuracy, or more independently verified reviews, and all seven alternatives score higher on ClickFraudTool’s independent benchmark.
ClickExpose is a UK-based digital marketing agency that also offers a click fraud protection tool. Founded in 2023 in Hoddesdon, Hertfordshire, and registered as CLICKEXPOSE LTD (UK company #14834804), the company is led by Vittoria Phillips and Raymond Sullivan. ClickExpose claims to manage over GBP 55 million in annual ad spend across its agency clients and employs between 10 and 49 staff covering all agency services. The company holds Google Partner status (#1000299776).
The click fraud tool provides 24/7 monitoring and automated blocking for Google Ads campaigns, with AI-based detection and session recordings. ClickExpose also offers a free monitoring plan (no blocking, no time limit) and a 30-day free trial on its paid Protect Pro plan. The key distinction from most competitors is that ClickExpose is an agency first and a fraud tool provider second. Click fraud protection is one service in a broader portfolio that includes PPC management, web design, and digital marketing.
The most common reason advertisers seek ClickExpose alternatives is platform coverage. ClickExpose protects Google Ads only. For the growing number of businesses running cross-platform campaigns on Google, Meta, and Microsoft, a tool that covers one platform leaves the rest of their ad spend unprotected. Alternatives like ClickPatrol, ClickCease, and ClickGuard include all three major platforms in their standard plans.
The second driver is detection confidence. ClickExpose’s 6.0/10 detection score and undisclosed methodology make it hard for advertisers to verify what is actually being caught. When you are paying to protect your ad budget, knowing how the tool distinguishes bots from real visitors matters. Competitors like ClickPatrol (9.9/10 detection, 800+ published data points) and ClickCease (2,000+ behavioral tests from CHEQ’s engine) provide more transparency.
Third, visit capacity. The 10,000 visit cap on the Pro plan is restrictive for advertisers with moderate traffic. A business spending GBP 5,000/month on Google Ads can easily exceed 10,000 clicks, at which point you either lose protection for the remainder of the month or need to negotiate an Agency plan at an undisclosed price. Competitors offer 25,000 to 75,000 clicks at similar or lower price points.
Fourth, protection depth. ClickExpose blocks clicks. That is the extent of its protection. It does not clean remarketing audiences, protect conversion data from bot contamination, or filter fake form submissions. Advertisers whose problems extend beyond click fraud to CRM spam, polluted bidding data, or inflated remarketing lists need broader protection.
Finally, independent verification. Without product-specific reviews on G2, Capterra, or Trustpilot, and with the Reviews.io score covering all agency services, buyers have limited independent data to evaluate the fraud tool on its own merits.
ClickExpose’s free monitoring plan and managed setup appeal to advertisers who want a low-commitment first step. But as campaigns grow and ad spend diversifies across platforms, the Google Ads-only limitation and 10,000-visit cap push many advertisers toward alternatives that match their expanding needs.
Best for: European advertisers, agencies, and e-commerce teams who need multi-layer click fraud protection with transparent pricing and GDPR compliance.
ClickPatrol is a Netherlands-based click fraud protection tool that analyzes 800+ data points per click with 99.97% bot detection accuracy. It offers four protection modules (AdProtector, AudienceProtector, DataProtector, and FormProtector) covering the full fraud lifecycle from click blocking to CRM spam prevention. Where ClickExpose focuses on Google Ads click blocking with session recordings, ClickPatrol covers three platforms with four layers of protection that extend well beyond the click itself.
Key features:
Supported platforms: Google Ads, META (Facebook and Instagram), Microsoft Advertising (Bing)
| Plan | Price | Clicks/month |
|---|---|---|
| Traffic Insights (Free Trial) | Free for 7 days | Up to 5,000 |
| Traffic Security Starter | EUR 59/month (annual) | Up to 75,000 |
| Traffic Security PRO | EUR 69/month (annual) | Up to 75,000 |
| Agency / Brand | On request | Unlimited |
No setup costs, no lock-in contracts. 17% discount on annual billing. 7-day free trial with full access.
What users say:
“Within 2 weeks our ROAS improved and the fake traffic just disappeared. The price pays for itself many times over.” – E-commerce ad manager, Trustpilot (March 2026)
“ClickPatrol feels like a tool designed by people who actually understand digital marketing pain points. The UI is clean, the fraud detection is accurate, and I can prove ROI improvements quickly to stakeholders.” – James W., Head of Marketing, G2 (September 2026)
“We were losing about 15 to 20% of our budget to junk clicks. Competitors clicking our ads, bots, you name it. ClickPatrol was super easy to set up and within the first week we could already see how many fraudulent clicks were being blocked.” – Dental clinic chain advertiser, Trustpilot (March 2026)
Pros:
Cons:
Ratings: G2: 4.7/5 | ClickFraudTool: 9.3/10 (Editor’s Choice)
Ideal use case: A mid-size e-commerce advertiser or agency spending EUR 3,000 to 30,000/month on Google Ads, Meta, and Microsoft Ads in a competitive niche (legal, insurance, SaaS), dealing with rising CPAs and junk leads, who needs fast setup with transparent pricing and multi-platform protection from day one.
Recommendation: ClickPatrol is the strongest ClickExpose alternative for advertisers whose campaigns span more than Google Ads. The four-module approach (ads, audiences, data, forms) covers protection layers that ClickExpose does not offer, and the 75,000 click capacity dwarfs ClickExpose’s 10,000 limit. If you value session recordings, ClickCease is the alternative that combines strong detection with visual visitor evidence.
Best for: Marketers who want battle-tested detection from CHEQ’s engine combined with session recordings and competitive intelligence.
ClickCease is the largest click fraud tool in the SMB market, with 14,000+ customers and 2M+ protected campaigns. Acquired by cybersecurity company CHEQ in 2020, it shares the same 2,000+ behavioral tests per visit that power CHEQ’s enterprise platform. Like ClickExpose, ClickCease includes session recordings. Unlike ClickExpose, it also adds competitive intelligence (AdSpy), supports multiple platforms, and has extensive independent review coverage.
Key features:
Supported platforms: Google Ads, META (Facebook and Instagram), Microsoft Ads (manual CSV), YouTube
Pricing:
| Plan | Monthly | Annual (save 15%) | Websites |
|---|---|---|---|
| Starter | $84/mo | $63/mo | 1 |
| Pro | $104/mo | $78/mo | Up to 5 |
| Advanced | $124/mo | $93/mo | Up to 20 |
| Enterprise (CHEQ) | Custom | Custom | Unlimited |
7-day free trial on all plans. Note: “protected visits” count ALL website traffic (organic, direct, referral, paid), not just ad clicks. Annual billing commitment required at these prices.
What users say:
“I saved more than 30% of my yearly budget for 2024-2026. The dashboards and reports are clear and easy to understand. And if something is not clear or does not work, the technical support team helps within a minute, literally a minute!” – Verified advertiser, Trustpilot (August 2026)
“I signed up after the pricing was presented as ‘$275/month.’ The page gave a strong month-to-month impression. Only in much smaller text was it indicated this monthly price was tied to an annual commitment.” – Verified reviewer, Trustpilot (January 2026)
Pros:
Cons:
Ratings: G2: 4.6/5 (107 reviews) | Capterra: 4.7/5 (222 reviews) | Trustpilot: 4.4/5 (510 reviews)
Ideal use case: A digital marketing agency managing 5 to 15 client accounts on Google Ads that wants fraud protection using a proven detection engine, session recordings for client reporting, and competitive intelligence for campaign strategy.
Recommendation: ClickCease is the best ClickExpose alternative for teams that value session recordings but want them backed by a stronger detection engine (2,000+ tests vs ClickExpose’s undisclosed methodology). The CHEQ enterprise pedigree and 14,000+ customer base give it significant scale and credibility advantages. Watch for the annual billing commitment and visit counting model. For more transparent pricing and form protection, ClickPatrol is the main competitor at this tier.
Best for: Mid-to-large advertisers running campaigns across many ad platforms (Google, Meta, TikTok, LinkedIn, Reddit, and more) who want cross-channel invalid traffic intelligence.
Lunio is a UK-based (Manchester) invalid traffic protection platform that uses a self-learning AI algorithm to detect and block fraudulent clicks across 13+ ad platforms. Its standout feature is cross-channel intelligence: when an invalid IP is detected on one platform, it is automatically excluded across all connected platforms. Where ClickExpose covers a single platform, Lunio covers more than a dozen.
Key features:
Supported platforms: Google Ads, META, Microsoft Ads (detection only), TikTok, LinkedIn, X/Twitter, Reddit, Snapchat, Pinterest, Yandex, Naver, AdRoll, and native ad platforms
Pricing: Custom (contact sales). Lunio does not publish pricing on its website. Historical references suggest starting around $49 to $60/month for small accounts, but current pricing cannot be independently verified.
What users say:
“Since making the changes Lunio recommended, the issues we were having with lead quality have improved massively. We generated more qualified pipeline in the two months after switching on traffic protection than we had done in the previous two years.” – Mandee Richards, Head of Marketing, Canto
“No cancellation option exists in the dashboard, no billing controls are available, and support did not respond to multiple termination requests.” – Capterra reviewer
Pros:
Cons:
Ratings: G2: 4.6/5 (~140 reviews) | Capterra: 4.6/5
Ideal use case: A mid-to-large advertiser spending $10K to $100K/month across Google Ads, Meta, TikTok, and LinkedIn, who needs one platform to detect and block invalid traffic across all channels with minimal hands-on management.
Recommendation: Lunio is the best ClickExpose alternative for multi-platform advertisers who have outgrown single-platform protection. The cross-channel intelligence and 13+ platform coverage represent a fundamentally different tier of protection than ClickExpose’s Google Ads-only model. The hidden pricing is a drawback. For Google Ads and Meta only, ClickPatrol or ClickCease offer better value with transparent pricing.
Best for: Data-driven PPC managers and agencies who want maximum control over blocking rules, thresholds, and fraud forensics.
ClickGuard differentiates itself through deep customization. With 50+ configurable features, a four-layer protection system, and both automation and granular manual controls, it gives experienced advertisers the ability to fine-tune fraud detection to their exact campaign needs. Where ClickExpose offers a straightforward managed approach, ClickGuard puts every knob and dial in your hands.
Key features:
Supported platforms: Google Ads (all campaign types including PMax), Microsoft Ads, META (Facebook and Instagram)
Pricing:
| Plan | Monthly | Websites | Ad Spend Cap |
|---|---|---|---|
| Lite | $74/mo | 1 | Up to $5K |
| Standard | $119/mo | 3 | Up to $50K |
| Pro | $159/mo | Unlimited | Up to $100K |
| Custom | Contact sales | Unlimited | Unlimited |
20% off with annual billing. 7-day free trial, no credit card required.
What users say:
“ClickGuard has the most customization options I’ve seen in any click fraud tool. I can set different rules for different campaigns and actually see the forensic data behind every blocked click.” – Verified G2 reviewer
“Setup takes about 30 to 45 minutes to fully configure compared to 5 minutes for simpler tools. But once it’s dialed in, the level of control is unmatched.” – Agency PPC manager, Capterra
Pros:
Cons:
Ratings: G2: 4.7/5 (~30 reviews) | Capterra: 4.8/5 (~155 reviews) | Trustpilot: 4.9/5 (181 reviews)
Ideal use case: A data-savvy PPC manager at an agency handling $50K to $100K/month in ad spend across multiple clients, who wants to set custom blocking rules per campaign and needs forensic-level visibility into every blocked click for client reporting.
Recommendation: ClickGuard is the best ClickExpose alternative for teams that want full control over their detection settings. The 50+ configurable features, forensic data, and unlimited clicks contrast sharply with ClickExpose’s managed-but-limited approach. The 30 to 45 minute setup time is longer than ClickExpose’s managed onboarding, but the resulting granularity is unmatched. For hands-off protection, ClickPatrol deploys faster.
Best for: Mobile app marketers, affiliate campaign managers, and APAC-based advertisers who need verification from impression through post-conversion events.
TrafficGuard is an Australian ad fraud prevention platform owned by Adveritas Limited (ASX: AV1), a publicly traded company. Founded in 2015 in Perth, it processes 3 trillion+ data points per month using ML/AI-powered statistical invalidation. TrafficGuard’s core differentiation is full-funnel verification: it tracks from impression through click, conversion, and post-conversion events. With native MMP integrations (Adjust, Kochava, AppMetrica), it covers mobile app fraud that neither ClickExpose nor most click fraud tools address.
Key features:
Supported platforms: Google Ads, META (enterprise only, from $250/mo), Mobile apps via MMP integrations, Affiliate networks (enterprise)
Pricing:
| Plan | Price | Details |
|---|---|---|
| Free | $0/mo | Detection only, up to $2,500 ad spend, no time limit |
| Shield | $49/mo | Full blocking, up to $30K ad spend, 30-day trial |
| Scale | Custom | $30K+ ad spend |
| Enterprise Meta | From $250/mo | Meta portfolio protection |
| Enterprise Mobile | From $2,500/mo | Full-funnel mobile verification |
What users say:
“I was suffering from tons of wasted clicks from bots and competitors, but TrafficGuard managed to block almost 95% of those clicks, increasing my ROI on ads.” – Gur T., Marketing Manager, SourceForge
“One of the worst click fraud services out there. The support never answer, they have a bot that sends you to a help portal and that would be it.” – Verified reviewer, Trustpilot
Pros:
Cons:
Ratings: G2: 4.4/5 (34 reviews) | SourceForge: 4.7/5 (89 reviews) | ClickFraudTool: 8.7/10
Ideal use case: An app-first company or performance agency running mobile campaigns across Adjust or Kochava, where mobile install fraud and post-install event fraud are the primary concerns.
Recommendation: TrafficGuard is the best ClickExpose alternative for mobile app marketers and affiliate campaign managers. The full-funnel approach and MMP integrations address an entirely different category of fraud than ClickExpose covers. For web PPC protection on Google, Meta, and Microsoft Ads, ClickPatrol or ClickCease offer better value and broader coverage at lower prices.
Best for: Small businesses and solo advertisers spending $2K to $25K/month on Google Ads who need straightforward click fraud protection at the lowest published price.
Fraud Blocker is a bootstrapped, Los Angeles-based tool founded by performance marketers with 45+ combined years of experience. It focuses on doing the basics well at transparent pricing. While it lacks the detection depth of ClickPatrol or the session recordings of ClickExpose, its proprietary fraud scoring, device fingerprinting, and automated IP blocking cover the fundamentals for advertisers on a tight budget.
Key features:
Supported platforms: Google Ads (full API), META (Facebook and Instagram, maturing), manual CSV export for other platforms
Pricing:
| Plan | Price | Clicks/month | Domains |
|---|---|---|---|
| Standard | $69/mo | 5,000 | 1 |
| Pro | $109/mo | 25,000 | 50 |
| Enterprise | From $469/mo | 250,000+ | Unlimited |
7-day free trial, no credit card required. 20% off annual billing. No contracts, cancel anytime.
What users say:
“Pays for itself and stellar customer service. Saves tons of money by stopping garbage and fraudulent ad clicks.” – Josh S., Business Owner
“I tried to open a ticket a week ago and still have not received an answer. The FraudBlocker reports are completely wrong.” – Verified purchaser, AppSumo
Pros:
Cons:
Ratings: G2: 4.3/5 | AppSumo: 4.3/5 (~80 reviews) | ClickFraudTool: 7.8/10
Ideal use case: A solo advertiser or small business spending $2,000 to $10,000/month on Google Ads in a local services niche (legal, HVAC, dentists), who needs basic click fraud protection without a big budget or technical complexity.
Recommendation: Fraud Blocker is the best ClickExpose alternative for budget-conscious advertisers who want transparent pricing and straightforward protection. The 7.8/10 ClickFraudTool score is a full point above ClickExpose’s 6.8/10, and the Pro plan’s 25,000 click capacity offers more room than ClickExpose’s 10,000. The small team means support can be slow, but the detection fundamentals are solid for small Google Ads accounts.
Best for: EU-based companies with strict GDPR compliance requirements who also need programmatic ad verification and clean analytics data.
Fraud0 is a Munich-based ad fraud detection platform (founded 2020) that analyzes 4,000+ data points per visitor using privacy-safe fingerprinting. It does not use cookies or collect personal data, making it fully GDPR Art. 6(f) compliant without requiring a consent banner. Where ClickExpose offers basic Google Ads protection from the UK, Fraud0 provides deep analytics and programmatic verification from the heart of the EU.
Key features:
Supported platforms: Google Ads, META (Facebook/Instagram), Microsoft Ads, TikTok, LinkedIn, DV360, programmatic display
Pricing:
| Plan | Monthly | Annual | Sessions |
|---|---|---|---|
| Starter | EUR 50/mo | EUR 40/mo | Up to 50K |
| Pro | EUR 150/mo | EUR 120/mo | Up to 100K |
| Enterprise | EUR 600/mo | From EUR 500/mo | From 100K+ |
7-day free trial, no credit card required. Programmatic protection and form fill protection are Enterprise-only features.
What users say:
“A very effective tool for killing unwanted traffic to our marketing channels. Since we are using fraud0 analytics suite, we can see precisely where fraudulent and low-quality traffic is coming from and react. Fraud0 significantly benefits our marketing budgets.” – Verified Trustpilot reviewer (November 2022)
“The setup was really easy and we love the clean dashboard. Very important to us is the fact that fraud0 is GDPR compliant.” – Verified Trustpilot reviewer (November 2022)
Pros:
Cons:
Ratings: G2: 4.9/5 (limited reviews) | Trustpilot: 3.8/5 (2 reviews) | ClickFraudTool: 8.0/10
Ideal use case: A European mid-market advertiser spending EUR 10,000 to 50,000/month across paid search, social, and programmatic display, who prioritizes GDPR compliance and needs clean analytics data alongside ad fraud protection.
Recommendation: Fraud0 is the best ClickExpose alternative for EU-based advertisers who need strong GDPR compliance with analytics cleansing and programmatic verification. The 4,000+ data points provide far more detection depth than ClickExpose’s undisclosed methodology, and the multi-platform coverage eliminates the Google Ads-only limitation. The thin review base requires patience. For faster deployment, ClickPatrol or ClickCease install and block within minutes.

Choosing the right alternative depends on why ClickExpose is not the right fit for your specific situation. Here is a decision framework based on the criteria that matter most.
Platform coverage beyond Google Ads
If you run Meta or Microsoft Ads alongside Google, ClickExpose does not protect that spend. For Google + Meta + Microsoft in one plan at base pricing: ClickPatrol (EUR 59/mo) or ClickGuard ($74/mo). For Google + Meta only: ClickCease ($63/mo annual). For broad multi-platform coverage (TikTok, LinkedIn, Reddit, and more): Lunio covers 13+ platforms. For Google + Meta + programmatic display: Fraud0 (from EUR 50/mo).
Detection confidence
If ClickExpose’s 6.0/10 detection score concerns you, every alternative in this list scores higher. ClickPatrol (9.9/10 detection) and ClickCease (2,000+ behavioral tests) offer the most documented detection engines. Fraud0 (4,000+ data points) provides the deepest per-visitor analysis. ClickGuard (50+ configurable features) gives you the most control over detection rules.
Visit capacity
If ClickExpose’s 10,000 visit cap on the Pro plan is too low, most alternatives offer significantly more capacity. ClickPatrol: 75,000 clicks. ClickGuard: unlimited clicks. Fraud Blocker Pro: 25,000 clicks. Fraud0 Starter: 50,000 sessions. TrafficGuard: based on ad spend (up to $30K at $49/mo).
Protection beyond click blocking
If you need more than click-level blocking: form/lead protection (ClickPatrol FormProtector), session recordings (ClickCease or Clixtell), audience cleaning (ClickPatrol AudienceProtector), conversion data hygiene (ClickPatrol DataProtector), analytics cleansing (Fraud0), mobile app fraud (TrafficGuard), or competitive intelligence (ClickCease AdSpy).
Budget and ad spend volume
For tight budgets on Google Ads only: Fraud Blocker ($69/mo, 5,000 clicks) or TrafficGuard Shield ($49/mo, up to $30K ad spend). For mid-range budgets with multi-platform needs: ClickPatrol (EUR 59/mo) or ClickCease ($63/mo annual). For larger budgets ($10K+/month ad spend): Lunio (custom pricing), Fraud0 (from EUR 150/mo for Pro), or ClickGuard Standard ($119/mo).
Data privacy and compliance
For strict EU data residency: ClickPatrol (Netherlands, ISO 27001/27018/27701) or Fraud0 (Munich, no cookies, GDPR Art. 6(f)). For UK compliance: Lunio (Manchester, SOC 2 + ISO 27001). TrafficGuard, ClickCease, Fraud Blocker, and ClickGuard are based outside the EU.
ClickExpose fills a specific niche: UK-based businesses running small Google Ads campaigns who want to start with free monitoring and prefer working with an agency that handles setup for them. The free plan and 30-day trial are genuinely useful for evaluation. But the Google Ads-only limitation, 10,000 visit cap, 6.0/10 detection score, and absence of independent product-specific reviews mean most growing advertisers will outgrow it quickly.
The most effective approach is to run a free trial with 2 to 3 tools that match your priorities and compare the invalid traffic data side by side. ClickExpose’s free monitoring plan, TrafficGuard’s free tier, Fraud0’s no-credit-card trial, and ClickPatrol’s 7-day full-access trial let you evaluate detection quality before committing any budget.
