# Proven exploits vs scanner alerts.

> Scanners pattern-match your code or fuzz endpoints and surface potential issues. Pensar attacks the running system and proves real exploits, including the chained attacks and business-logic flaws scanners structurally can't model.

## TL;DR

DAST and SAST scanners are cheap, broad, and fast, which makes them a fine baseline, but they report potential issues from patterns and signatures, generate heavy false-positive noise, and can't reason about your business logic or chain a multi-step attack. Pensar attacks the live system and returns only findings it has proven with a working exploit, plus the patch. Most teams keep a scanner for breadth and add Pensar for depth and proof.

## Dimension by dimension

| Dimension | Pensar | Vulnerability scanners |
| --- | --- | --- |
| What they actually test | Pensar exercises the running application the way an attacker would, so a reported finding is something that actually happened against your live system. | Scanners inspect source for risky patterns (SAST) or probe endpoints with known payloads (DAST). They flag what looks risky, not what's provably exploitable. |
| False positives and triage | Because every finding ships with a working proof of concept, there's nothing to dismiss as a false alarm. The triage step disappears. | Pattern matching produces noise. Teams spend significant time triaging scanner output to separate real issues from the many that aren't. |
| Business logic and chained attacks | Agents reason about your payment flows, access boundaries, and tenant isolation, then chain multiple steps into a verified takeover. | Scanners have no model of your business logic and evaluate issues in isolation, so the flaws that matter most to your specific app go unseen. |
| From finding to fix | Findings arrive as pull requests with the patch drafted, so remediation is a review-and-merge instead of a research project. | A scanner hands you an alert. Understanding it, confirming it, and writing the fix is left entirely to your team. |

## Frequently asked questions

### Is Pensar a SAST or DAST tool?

Neither. SAST reads source code and DAST fuzzes endpoints; both report potential issues. Pensar is an adversarial testing platform: autonomous agents attack the running system and prove real exploits, then ship the patch.

### Should I replace my scanner with Pensar?

Most teams keep a scanner for cheap, broad baseline coverage and add Pensar for depth and proof. Pensar removes the triage burden by only reporting findings it has verified with a working exploit.

### How does Pensar avoid false positives?

Every finding is proven by actually exploiting it against your live system and captured as a reproducible proof of concept. If Pensar reports it, it fired. There's no maybe to triage.

### Can scanners find business-logic flaws?

No. Scanners match patterns and signatures and have no model of how your application works, so business-logic flaws, the ones specific to your payment flows or access boundaries, fall outside what they can detect.
