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

The best TrafficGuard alternatives in 2026 are ClickPatrol (best overall value for SMBs and mid-market, from €59/mo with four protection modules), 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. Budget-conscious advertisers should consider Fraud Blocker, and local service businesses needing call tracking should look at Clixtell. Most advertisers who do not need mobile app fraud detection will find better value and broader platform coverage from one of these alternatives.
TrafficGuard is an Australian ad fraud prevention platform owned by Adveritas Limited (ASX: AV1), a publicly traded company on the Australian Securities Exchange. Founded in 2015 in Perth by CEO Mathew Ratty, the platform processes 3 trillion+ data points per month using ML/AI-powered statistical invalidation. TrafficGuard generates A$14.25 million in annual recurring revenue (January 2026) and employs approximately 43 staff dedicated to the TrafficGuard product, with roughly 80 across the Adveritas group.
TrafficGuard’s core differentiation is full-funnel verification. While most click fraud tools focus on the click itself, TrafficGuard tracks the entire journey: impression, click, conversion, and post-conversion events. This makes it particularly effective for mobile app marketers and affiliate campaigns, where fraud often appears legitimate at the click level but fails post-install analysis. The company is a Google Cloud and Google Ads Partner with native MMP integrations (Adjust, Kochava, AppMetrica).
The most common reason advertisers seek TrafficGuard alternatives is platform coverage at the base price. TrafficGuard’s $49/mo Shield plan covers Google Ads only. Adding Meta requires a separate enterprise plan ($250/mo), and Microsoft Ads is not supported at all. For advertisers running campaigns across Google, Meta, and Microsoft, alternatives like ClickPatrol, ClickCease, and ClickGuard include all three platforms in their standard plans.
The second driver is protection scope. TrafficGuard excels at full-funnel verification and mobile app fraud, but it lacks form/lead protection and session recordings. Advertisers whose primary pain point is junk form submissions or CRM spam find better solutions elsewhere.
Third, pricing at scale. The Shield plan is affordable at $49/mo, but the custom Scale tier can become expensive for larger advertisers. And the enterprise products (Meta from $250/mo, Affiliate from $1,500/mo, Mobile from $2,500/mo) add up quickly if you need multiple channels protected.
Finally, regional fit. TrafficGuard’s Australian base is an advantage for APAC advertisers but creates EU data residency questions for European companies with strict GDPR requirements.
“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. TrafficGuard’s detection is strong, but the platform coverage and pricing structure push many non-mobile advertisers to explore alternatives.
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 TrafficGuard focuses on full-funnel verification from impression to post-conversion, ClickPatrol focuses on making every layer of click-level protection accessible at SMB pricing.
Key features:
Supported platforms: Google Ads, META (Facebook and Instagram), Microsoft Advertising (Bing)
Pricing:
| Plan | Price | Clicks/month |
|---|---|---|
| Traffic Insights (Free Trial) | Free for 7 days | Up to 5,000 |
| Traffic Security Starter | €59/month (annual) | Up to 75,000 |
| Traffic Security PRO | €69/month (annual) | Up to 75,000 |

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 GDPR-proof protection from day one.
Recommendation: ClickPatrol is the strongest TrafficGuard alternative for advertisers whose primary concern is web-based click fraud and form spam. The four-module approach (ads, audiences, data, forms) covers protection layers that TrafficGuard does not offer, particularly FormProtector for CRM spam. However, if mobile app fraud detection or affiliate verification is your priority, TrafficGuard covers use cases that ClickPatrol does not.
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. Unlike TrafficGuard’s full-funnel approach, ClickCease focuses on click-level protection but adds unique extras: session recordings (visual proof of visitor behavior), AdSpy competitive intelligence, and WordPress bot protection.
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 TrafficGuard alternative for teams that value session recordings and competitive intelligence. The 2,000+ behavioral tests and 14,000+ customer base give it a scale advantage. 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 TrafficGuard excels vertically (full-funnel from impression to post-conversion), Lunio excels horizontally (broad platform coverage across 13+ networks).
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 TrafficGuard alternative for multi-platform advertisers who need cross-channel intelligence but do not need mobile app fraud verification or affiliate fraud detection. The hidden pricing model is a drawback it shares with TrafficGuard’s Scale tier. For Google Ads and Meta only, ClickPatrol or ClickCease offer better value with transparent pricing.
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. Its combination of onsite bot detection and in-ad programmatic verification gives it broader scope than most SMB tools, putting it closer to TrafficGuard’s ambition of covering more than just click fraud.
Key features:
Supported platforms: Google Ads, META (Facebook/Instagram), Microsoft Ads, TikTok, LinkedIn, DV360, programmatic display
Pricing:
| Plan | Monthly | Annual | Sessions |
|---|---|---|---|
| Starter | €50/mo | €40/mo | Up to 50K |
| Pro | €150/mo | €120/mo | Up to 100K |
| Enterprise | €600/mo | From €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 €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 TrafficGuard alternative for EU-based advertisers who need strong GDPR compliance with analytics cleansing. The 4,000+ data points and programmatic verification (Enterprise tier) provide depth that TrafficGuard does not offer at comparable pricing. The thin review base and detection-first setup mode require patience. For faster deployment, ClickPatrol or ClickCease install and block within minutes.
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 TrafficGuard provides intelligence at the funnel level, ClickGuard provides control at the campaign level.
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 TrafficGuard alternative for teams that want full control over their detection settings. The 50+ configurable features and forensic data are unmatched. But the 30 to 45 minute setup time and learning curve make it less suited for small teams. For hands-off protection, ClickPatrol or Fraud Blocker deploy faster. For mobile or affiliate fraud, TrafficGuard remains the better option.
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 TrafficGuard’s detection sophistication and full-funnel capabilities, 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 most budget-friendly TrafficGuard alternative with honest, transparent pricing and easy setup. It handles the basics well for small Google Ads accounts. However, the small team means support can be slow, and the detection engine is far less advanced than TrafficGuard, ClickPatrol, or Fraud0. If your ad spend grows past $25K/month, consider upgrading to a more capable tool.
Best for: Local service businesses (plumbers, lawyers, dentists) that rely on phone calls from ads and need click fraud protection combined with call tracking in one platform.
Clixtell bundles three capabilities into one platform: click fraud detection, call tracking with recording and attribution, and session recording. This makes it unique for businesses that generate leads through phone calls and need to verify both click quality and call quality. Plans start at just $15/month for monitoring. ClickFraudTool scored Clixtell 7.5/10 overall, describing detection as “competent but not sophisticated.”
Key features:
Supported platforms: Google Ads (full support), Microsoft Ads (limited, IP blocking only), Meta (recently added)
Pricing:
| Plan | Price | Details |
|---|---|---|
| Monitor | $15/mo | Detection only, up to 5,000 ad clicks, 1 domain |
| Protection | $50/mo | Full blocking, AI fraud algorithms, up to 10,000 clicks |
| Agency | $75/mo | Unlimited websites and accounts, dedicated manager |
14-day free trial. 20% off annual billing. Call tracking available as add-on from $10/mo.
What users say:
“Easy to use and have been able to receive refunds from Google in the past 30 days that would cover my account cost for the year.” – Verified reviewer, Trustpilot (July 2026)
“Great support from their team, almost instant responses. The software is easy to use, and prices are competitive.” – Verified reviewer, Trustpilot (May 2024)
“No support for smart campaigns… this service doesn’t work for smart campaigns.” – Verified reviewer, Trustpilot (February 2024)
Pros:
Cons:
Ratings: Trustpilot: 4.1/5 (37 reviews) | FeaturedCustomers: 4.8/5 (1,570 ratings) | ClickFraudTool: 7.5/10
Ideal use case: A local service business (legal, dental, home services) spending $1,000 to $5,000/month on Google Ads that generates leads through both form submissions and phone calls and needs fraud protection and call tracking in one platform without paying for multiple subscriptions.
Recommendation: Clixtell is the best TrafficGuard alternative if you need call tracking bundled with fraud detection. The fraud detection alone is not as strong as dedicated tools, but the bundle eliminates the need for a separate call tracking solution. For advertisers who do not rely on phone leads, ClickPatrol or ClickCease offer stronger fraud detection. For mobile app fraud, TrafficGuard remains the better option.

Choosing the right alternative depends on why TrafficGuard is not the right fit for your specific situation. Here is a framework based on the criteria that matter most.
Budget and ad spend volume
TrafficGuard’s Shield plan ($49/mo) is affordable for Google Ads-only protection up to $30K ad spend. But adding Meta ($250/mo) or mobile ($2,500/mo) increases costs quickly. If you need Google + Meta + Microsoft at a predictable price, ClickPatrol (€59/mo) and ClickCease ($63/mo annual) include all core platforms. For tight budgets, Clixtell starts at $15/mo and Fraud Blocker at $69/mo.
Supported ad platforms
TrafficGuard excels at Google Ads and mobile app fraud but lacks Microsoft Ads and gates Meta behind enterprise pricing. For Google + Meta + Microsoft in one plan: ClickPatrol, ClickGuard, or Fraud0. For broad multi-platform coverage (TikTok, LinkedIn, Reddit): Lunio covers 13+ platforms. For Google Ads only at the lowest price: TrafficGuard’s free tier or Clixtell’s $15/mo monitoring.
Protection scope beyond click fraud
If you need form/lead protection: ClickPatrol (FormProtector). If you need session recordings: ClickCease or Clixtell. If you need call tracking: Clixtell is the only option. If you need analytics cleansing: Fraud0. If you need mobile app fraud or affiliate fraud, TrafficGuard remains the strongest option in those categories.
Technical setup and control preferences
If you want hands-off protection in minutes: ClickPatrol (under 1 minute) or Fraud Blocker (~5 minutes). If you want maximum per-campaign customization: ClickGuard (50+ configurable features, 30 to 45 minutes to set up). If you want to evaluate without any commitment: TrafficGuard’s free tier or Fraud0’s 7-day trial (no credit card).
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 Clixtell are based outside the EU.
TrafficGuard is a genuinely strong platform with unique capabilities in mobile app fraud detection, full-funnel verification, and financial transparency as a publicly listed company. For mobile app marketers and affiliate campaign managers, it remains the best option in its category. For everyone else, the alternatives above cover common advertiser needs at lower prices with broader platform support.
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. 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.
