dynamic Application Security Testing (DAST)

Dynamic application security testing that never sleeps

Your pen test captures one day. Your application changes every week. Fencer runs continuous DAST scanning against your live app automatically, surfacing runtime vulnerabilities your code scanner can't catch.

Why Fencer for DAST

DAST for lean teams

COntinuous, not point-in-time

Your application ships new code constantly. Fencer scans continuously so vulnerabilities don't sit undetected between penetration tests.

Catch what SAST misses

Static analysis checks your source code. DAST attacks what's actually running. CSP headers, CSRF risks, and cookie flags only show up at runtime.

One platform for security

DAST findings land in the same place as your code, infrastructure, and dependency findings. One platform for your security essentials, not another standalone tool.

Capabilities

Find runtime vulnerabilities before attackers do

Continuous APPlication Scans

Continuous automated scanning with no gaps in coverage

Fencer scans your live application on a continuous schedule automatically. Every scan is logged with a timestamp, vulnerability counts, and a trends view so you can see your posture change over time.

RUNTIME VULNERABILITY DETECTION

Runtime vulnerability detection your code scanner can't do

Fencer's DAST engine probes your running application in the way an attacker would, finding vulnerabilities that only appear at runtime. Every finding includes severity, the exact URL where it was detected, and remediation guidance.

Severity ratings: Critical, high, medium, and low so you know what to fix first
Exact URL location: Every finding links to the specific endpoint where the issue was detected
Remediation guidance: Each finding includes the risk and specific fix instructions

SCAN TARGET CONFIGURATION

Web and API scanning with automatic endpoint discovery

Define what Fencer scans using manual URLs, a site map, an open API spec, or a GraphQL schema. For APIs, Fencer automatically maps your endpoints from the spec. No manual URL enumeration required. Authenticated scanning covers any part of your app that requires a login.

Open API and GraphQL support: Provide your spec or schema, and Fencer maps and scans your API endpoints automatically
Authenticated scanning: Supports Basic Auth, Bearer Token, Custom Header, and Login Forms
Rate Limit Control: Configurable requests per second so scans don't impact your application

use Cases

What can you do with Fencer's DAST?

Replace your annual pen test with continuous coverage.

A pen test shows you your posture on one day of the year. Your application changes every other day. Fencer scans continuously so you catch vulnerabilities as they're introduced, not eleven months later.

Satisfy SOC 2 continuous monitoring requirements.

SOC 2 and other common compliance frameworks require evidence of ongoing security monitoring. Fencer's continuous scan history gives auditors timestamp records of findings, resolutions, and posture trends with no extra work on your end.

"We want to make sure we're continuously checking our security posture, as opposed to periodic things like pen tests, and with Fencer's DAST, we're doing so in a more robust way than static analysis alone."
