Protect

Detection is fine. Stopping the attack is better.

When 10 million records can disappear in seconds, security has to move at network speed. Wallarm detects API attacks and blocks them in real time — protecting your APIs, AI applications, and MCP servers before damage is done.

The Problem

API Is the Attack Surface.
AI Is the Risk Multiplier.

APIs power your business. AI multiplies them. And attackers only need one weak endpoint to win.

97%

of API vulnerabilities can be exploited with a single request.

59%

of API vulnerabilities require no authentication.

43%

of exploitable vulnerabilities are API related.

Types of Attacks

SQL Injection

Attackers don’t need fancy AI when a simple injected query will do. SQL injection manipulates backend database calls through API inputs to read, modify, or delete data. It’s old-school, but it still works.

Business Logic Attack

No vulnerability required. Attackers exploit the way your application is supposed to work — skipping steps, reusing coupons, bypassing authorization. Traditional tools miss this because technically, everything looks “valid.”

AI Logic Abuse

AI systems make decisions. Attackers manipulate those decisions. By abusing model workflows or logic paths, they push AI systems to produce unsafe, manipulated, or high-risk outcomes.

Prompt Injection

When attackers sneak malicious instructions into prompts, they can override safeguards, extract sensitive data, or alter model behavior. If your AI runs on APIs, this becomes your problem fast.

API Abuse

Sometimes nothing is “broken.” The API just gets used in ways it was never intended to be used — at scale, automatically, and for fraud. Abuse drains revenue quietly unless you’re watching for it.

The Solution

API Protection
That Actually Works

Deep Request Inspection

APIs aren't uniform, and attackers love that. Encoded payloads, protocol tricks, padding — all designed to slip past shallow inspection. Wallarm sees through it and stops what others miss.

Block Business Logic Abuse

Your code can be secure and still lose money. Attackers exploit workflows, not just vulnerabilities — and AI makes it easier for them. Wallarm identifies and stops logic abuse in real time, before it becomes revenue loss.

Secure AI Transformation

AI runs on APIs. Which means AI security is API security. Wallarm protects your AI apps, API endpoints, and MCP servers — blocking exploits, catching anomalies, and keeping innovation from becoming exposure.

Protect API Revenue

APIs process payments, power partner integrations, and move real money. If they fail or get abused, revenue stops. Wallarm uses transaction-aware telemetry and agentic AI to stop fraud in-session.

Stop Account Takeovers

Credential stuffing, brute force, low-and-slow attacks — they're all targeting your APIs. Wallarm detects automated abuse at authentication points and shuts it down without punishing legitimate users.

Enforce API Specifications

Blocking bad traffic is good. Allowing only known-good traffic is better. When specifications are available, Wallarm enforces them as a positive security model — including for MCP servers.

Capabilities

Built for Real-Time Defense

Real-Time Inline Blocking

Wallarm inspects API traffic and blocks malicious requests immediately — not after the alert, not in tomorrow's report. Inline protection stops injections, account takeovers, and abuse as they happen. No application changes required.

Credential Stuffing Detection

Wallarm identifies automated login attempts using compromised credentials — including low-and-slow campaigns that fly under the radar. By analyzing authentication behavior in real time, it protects accounts without disrupting legitimate users.

API Abuse Prevention

Not all attacks look like exploits. Wallarm detects scraping, data harvesting, workflow manipulation, and other misuse of legitimate API functionality. That means fraud gets stopped before it turns into lost revenue.

Custom Mitigation Controls

Every API environment is different. Wallarm provides flexible mitigation controls that let you tailor protection policies to your specific applications, traffic patterns, and risk tolerance.

API Session Visibility

Security decisions are better with context. Wallarm correlates requests into sessions so you can see behavior across time — investigate attacks, track abuse patterns, and respond accurately instead of reactively.

Passive Vulnerability Detection

Wallarm doesn't just stop attacks. It continuously analyzes real production traffic to identify vulnerabilities based on how your APIs are actually used. No scanning noise. No performance impact. Just actionable risk visibility.

"Wallarm really protects our service and provides good visibility and user-friendly control."

Anton Bulavin

Head of Application Security

"I would absolutely recommend Wallarm, in a heartbeat. They do what they say on the tin – meaning what they say they can do, they really do."

Rob Davies

VP of Engineering and Lead Architect

“We didn’t need to change anything in the application deployment infrastructure. The installation itself is easy and straightforward.”
