HUMAN Security Alternative:
Why Teams Switch to IPASIS

HUMAN Security (formerly PerimeterX) is one of the biggest names in bot management. They verify over 20 trillion digital interactions weekly, run 400+ ML algorithms, and count Fortune 500 companies among their clients. They're impressive—and their pricing reflects it.

But here's the thing: most teams searching for bot detection aren't Fortune 500 companies. They're SaaS builders with 5,000 users. E-commerce stores doing $200K/month. Gaming platforms that need to stop multi-account abuse. And for these teams, HUMAN Security's enterprise-first model creates real friction.

This article breaks down where HUMAN Security excels, where it falls short for smaller teams, and why IPASIS is built for the segment HUMAN doesn't serve.

What HUMAN Security Does Well

Credit where it's due. HUMAN Security built a serious platform:

• Scale: 20T+ interactions verified weekly across 3B+ unique devices. Their telemetry network is massive, which means better signal quality for detecting sophisticated bot patterns.
• Decision Engine: Analyzes 2,500+ signals per interaction in milliseconds. This isn't simple IP blocklisting—it's behavioral analysis, device fingerprinting, and ML-driven anomaly detection.
• Breadth: They cover ad fraud, account takeover, content scraping, fake accounts, transaction abuse, client-side supply chain attacks, and even agentic AI governance.
• Enterprise integrations: Deep CDN integrations (Cloudflare, Akamai, Fastly), load balancer hooks, and application SDKs for seamless deployment in complex infrastructure.

If you're a $100M+ revenue company with a dedicated security team and a six-figure annual budget for bot management, HUMAN Security is a strong choice. They earned their position.

The Problem: Enterprise-Only by Design

HUMAN Security doesn't publish pricing on their website. There's no free tier. There's no self-serve signup. Every path leads to “Get a Demo” or “Talk to a HUMAN.”

This is by design—and it creates several problems for smaller teams:

1. Opaque Pricing

Industry reports place HUMAN Security contracts in the $50,000-$300,000+/year range, depending on traffic volume and product modules. The minimum engagement typically starts at $3,000-5,000/month. For a startup burning $30K/month total, that's 10-15% of your entire budget on bot detection alone.

2. Sales-Gated Onboarding

You can't try HUMAN Security without talking to sales. The typical onboarding process involves demo calls, proof-of-concept evaluations, contract negotiations, and implementation support. This is standard for enterprise security—but it means weeks to months before you block a single bot.

3. Integration Complexity

HUMAN's platform requires deploying JavaScript sensors on your pages, configuring CDN-level integrations, and setting up enforcement rules. Their documentation references “solutions engineers” and “dedicated support” because the integration isn't trivial. Compare that to a single API call.

4. Overkill for Most Use Cases

HUMAN's 2,500+ signals and 400+ algorithms are built to catch nation-state-level bot operators running million-dollar fraud operations. If your problem is “bots are creating fake accounts” or “scrapers are hitting my API,” you're paying for a fighter jet when you need a guard dog.

IPASIS vs HUMAN Security: Side-by-Side

Where IPASIS Wins

1. Instant Access, Zero Friction

Sign up, get an API key, make your first query. That's it. No demo calls, no sales qualification, no “let me check with my manager.” Your engineering team can evaluate IPASIS in a lunch break. With HUMAN Security, you're looking at a multi-week procurement process before writing a single line of integration code.

2. Transparent, Predictable Pricing

IPASIS publishes its pricing. The free tier gives you 1,000 requests/day—enough for early-stage products to ship bot detection from day one. Paid plans scale predictably. You know what you're paying before you commit. HUMAN Security requires custom quotes and annual contracts.

3. Server-Side Simplicity

IPASIS works entirely server-side. Pass an IP address, get back a trust score and risk signals. No JavaScript tags on your frontend, no CDN configuration, no client-side SDK to maintain. This matters because:

• No performance impact on your website's loading speed
• Works for APIs, not just web pages — protect your REST endpoints, webhooks, and mobile backends
• No client-side circumvention — bot operators can't disable or manipulate server-side checks
• Privacy-friendly — no additional tracking scripts on your users' browsers

4. Purpose-Built for the Mid-Market

HUMAN Security optimizes for enterprises with dedicated security teams. IPASIS is built for engineering teams that need to add bot detection alongside their other work—not as a full-time project. The API is designed to be integrated in minutes, not weeks.

Where HUMAN Security Wins

Fairness matters. HUMAN Security has genuine advantages for the right use case:

• Behavioral analysis depth: Their client-side sensors capture mouse movements, keystroke patterns, and touch gestures. This catches sophisticated bots that mimic normal browsing patterns—something server-side IP intelligence alone can't do.
• Ad fraud protection: If you're a publisher or ad platform, HUMAN's advertising solutions (formerly PerimeterX Code Defender) provide specialized ad fraud detection that IPASIS doesn't offer.
• Client-side supply chain protection: Their Client-Side Defense product monitors third-party scripts on your pages for malicious behavior—a different problem space entirely.
• Massive telemetry network: 20T+ interactions weekly means their ML models have more training data than almost anyone. For detecting novel, zero-day bot attacks, this scale advantage matters.

The Architectural Difference

This comparison isn't just about features—it's about fundamentally different approaches to bot detection:

HUMAN Security: Client-Side Behavioral Detection

HUMAN deploys JavaScript sensors that observe user behavior in the browser. The sensor collects device characteristics, interaction patterns, and environmental signals, then sends them to HUMAN's Decision Engine for classification. This approach excels at catching bots that execute JavaScript and try to mimic human behavior.

Trade-off: Requires JavaScript execution, adds latency to page loads, doesn't protect headless API calls, and can be circumvented by advanced bot operators who modify or disable the sensor.

IPASIS: Server-Side IP Intelligence

IPASIS analyzes the IP address of incoming requests against continuously updated threat intelligence feeds. Every IP gets a trust score based on VPN/proxy detection, datacenter identification, abuse history, ASN reputation, and geographic anomalies. Detection happens server-side before your application even processes the request.

Trade-off: Can't detect behavioral patterns like mouse movements or typing cadence. Focused on network-level signals rather than application-level behavior.

The Smart Play: Layered Detection

Many security teams use both approaches. IPASIS as the first line of defense—cheap, fast, server-side filtering that blocks known bad traffic before it reaches your application. Then behavioral detection (whether HUMAN or another tool) for the traffic that passes through. This layered approach gives you the best coverage without overpaying for enterprise bot management on every request.

Who Should Use IPASIS Instead of HUMAN Security?

• SaaS platforms that need to stop fake signups and account abuse without an enterprise budget
• E-commerce stores fighting checkout bots and payment fraud
• API-first companies that need to protect endpoints (not just web pages)
• Gaming platforms dealing with multi-account abuse and proxy detection
• Startups that want fraud detection from day one without sales calls or contracts
• Teams evaluating HUMAN Security who find the pricing or complexity doesn't match their scale

Who Should Stick With HUMAN Security?

• Enterprise companies with dedicated security teams and $50K+ annual bot management budgets
• Ad platforms and publishers that need specialized ad fraud detection
• Organizations that need client-side behavioral analysis (mouse tracking, keystroke dynamics)
• Companies already in HUMAN's ecosystem with existing integrations and SLAs

Getting Started

If you're evaluating HUMAN Security and wondering whether the enterprise approach is right for your scale, try IPASIS first:

1. Sign up for a free API key — no credit card, no sales call
2. Make your first query in under 2 minutes
3. Evaluate the trust scores and risk signals against your traffic
4. Decide if server-side IP intelligence solves your problem—or if you need to add behavioral detection on top

Most teams find that server-side IP intelligence catches 80-90% of bot traffic at a fraction of the cost. For the remaining 10-20%, you can layer on behavioral tools as needed—without locking into an enterprise contract from day one.
