Security that keeps
running without you.
AI driven, continuous and autonomous security management. S4E watches your attack surface, scans when it changes and tells you what to fix first.
From one-off scans
to continuous exposure management.
Continuous Threat Exposure Management turns scanning into a loop that never stops. S4E runs the loop for you.
1. Watch
2. Scan on change
3. Prioritise
4. Act
Autonomous, not unattended.
AI does the repetitive work. You stay in control of what gets fixed and when.
Continuous scanning
Change-aware scans

Scans that
never stop.
Schedule recurring scans across your entire attack surface. The Scheduler runs 24/7: new subdomains, expired certificates, open ports, fresh CVEs, and newly vulnerable packages inside your servers when Inside depth is on. You get notified, not surprised.
Start continuous monitoring →Describe it.
AI scans it.
No coding needed. Describe what you want to test the AI generates the exact code, executes it on the S4E engine, and delivers real-time results you can review, tweak, and re-run.
Check if our checkout page leaks card data to 3rd-party scripts, and verify session tokens expire after password reset.
I've generated a targeted scan based on your requirements. Here's what I created:
import requests from bs4 import BeautifulSoup def check_pci_leak(url): """Check outbound requests for PCI data""" resp = requests.get(url, timeout=10) soup = BeautifulSoup(resp.text, "html.parser") scripts = [ src["src"] for src in soup.find_all("script", src=True) ] return { "third_party": scripts, "risk": "HIGH" if len(scripts) > 5 else "LOW" }
Plug S4E
into your stack.
REST API, MCP protocol, webhooks, CI/CD pipelines. Build security into your workflow programmatically trigger scans, consume results, and automate remediation.

Full programmatic access to scans, results, assets, and reports.
MCP Protocol
Connect S4E to AI agents and LLM workflows as a tool provider.
CI/CD
Run security checks in your deployment pipeline. Block on critical findings.
Start free,
or go inside the server.
External Scanning
Manual scans of your internet-facing assets, from the outside, like an attacker.
Credentialed Scanning
Add a server login and S4E also looks inside the server for outdated, vulnerable software.
