DAST built for modern applications.
Modern apps are single-page, JavaScript-heavy, and form-heavy. NightVision drives a real browser and tests the app fully authenticated.
How the crawler is different
Three mechanisms separate NightVision from a link-following spider.
Forms get filled, not abandoned
Each rendered form is filled with valid, internally consistent values, so validation-gated submits fire the underlying API.
Pages tested when actually ready
No fixed timers: the crawler watches network and DOM mutation events over WebDriver BiDi and advances only when both quiesce.
Large apps stay scannable
DOM, URL, and action signatures collapse templated pages to one logical state, so scan budget goes to genuinely distinct surface.
Built for the apps you actually ship
Real browser, real routes, real state
React, Angular, and Vue apps are driven in a real browser. A plain HTTP fetch sees an empty <div id="root">; NightVision sees the application.
Test the fully authenticated app
Record your login once as a Playwright script: credentials vault automatically, TOTP-based MFA runs at scan time, and the session is verified first. How authenticated scanning works →
Internal apps without infrastructure changes
The Smart Proxy reaches internal, pre-production, and network-segmented apps: no agents, no appliances, no routing changes. Private network scanning →
The endpoints your traffic never shows
Source intelligence maps routes from your code in under 20 seconds and adds documented and shadow routes to the API scan. API discovery from source code →
AI endpoints get their own tests.
NightVision tests whether an endpoint backed by a language model can be steered into calling out to an attacker or reading your cloud metadata service, and reports those only with proof.

Findings developers act on, not tickets they dispute
Runtime evidence behind the finding
Request-level findings retain the relevant HTTP exchange, can produce a curl reproduction, and export as SARIF into GitHub Security Alerts. DAST in your CI/CD pipeline →
Endpoint source context where supported
On supported API scans backed by source intelligence, findings resolve to the defining file and line for fix and rescan before review. Remediation and learning →
That determinism makes NightVision findings safe inputs for coding agents via MCP. See how NightVision is agent-ready →

| Capability | Traditional traffic-based DAST | NightVision |
|---|---|---|
| SPA / JavaScript-rendered coverage | ⚠️ Partial, or static HTML only | ✅ Real browser, routes followed |
| Validation-gated forms | ❌ Abandons at required fields | ✅ LLM form handling completes the flow |
| Authenticated scanning | ⚠️ Often breaks silently at login | ✅ Recorded login, TOTP/MFA, login-check gate |
| Internal / private-network apps | ⚠️ Agents or appliances required | ✅ Smart Proxy, zero infrastructure changes |
| Undocumented API coverage | ❌ Only endpoints seen in traffic | ✅ OpenAPI specs generated from source |
| AI / LLM-backed endpoints | ⚠️ Treated like any other endpoint | ✅ Dedicated tests that report only with proof |
| Which apps get tested | ⚠️ Only what someone onboarded | ✅ App discovery finds apps tied to your domain (Enterprise) |
| Triage memory | ⚠️ Dismissed findings can return every scan | ✅ False positives you mark stay suppressed |
| Finding evidence | ⚠️ Alert with a payload | ✅ Full request/response; file:line on supported source-discovered API findings |
DAST questions, answered.
What is DAST?
Dynamic Application Security Testing tests a running application from the outside, sending real requests and analyzing responses to find vulnerabilities like SQL injection, XSS, and authentication flaws. NightVision adds source awareness: request-level findings retain the HTTP exchange, and supported source-discovered API findings can tie back to the defining file and line.
Can NightVision scan single-page applications?
Yes. The crawler drives React, Angular, and Vue apps in a real browser, follows client-side routes, and advances only when network activity and DOM mutations have settled, so dynamically rendered content is fully loaded before testing.
Does NightVision scan fully authenticated?
Yes. Record your login once as a Playwright script; credentials are extracted to a secrets vault automatically, and NightVision scans as a signed-in user, TOTP-based MFA included. A login-check gate fails the pipeline if authentication did not succeed.
Does NightVision test AI and LLM endpoints?
Yes. NightVision tests whether an endpoint backed by a language model can be steered into calling out to an attacker or reading your cloud metadata service, and reports those only with proof. It also flags endpoints it recognizes as model-backed. These tests are part of NightVision's standard DAST check set. See how the cloud metadata check works.
