We tell you what to fix first

A typical scanner marks half your findings “critical”. We put on top what hackers use right now.

Frequently asked questions

How do I check a website for vulnerabilities?

Enter your domain and verify ownership with a DNS TXT record. signalfort finds subdomains, services and technologies, matches software versions against CVE and FSTEC BDU, and lists the vulnerabilities by priority. First results arrive in 10 minutes.

Do you need access to our servers?

No. We look at your company from the outside, the way an attacker does, and check only what is reachable from the internet. No agents to install, no passwords to share.

How is signalfort different from a vulnerability scanner?

A scanner hands you a long list of possible issues. We safely check every finding, keep the real threats and put on top what is already used in attacks, based on CISA KEV and EPSS.

What vulnerabilities do you find?

Exposed .env and .git files, database backups, services with no password (Elasticsearch, Redis, Spring Actuator), leaked keys and tokens, outdated software with known CVEs, and TLS certificate problems.

Do you support FSTEC BDU and regulatory reports?

Yes. Vulnerabilities are matched against FSTEC BDU, CVE, GHSA, OSV and EUVD, and reports for leadership and regulators come in FSTEC and CRA formats.

How much does signalfort cost?

Radar is free: passive perimeter monitoring and a vulnerability feed for your stack. Active checks, confirmed findings and SLA come with the Contour plan, priced on request.
