External attack surface monitoring.
Assay scans your internet-facing systems for exposed services, vulnerable software and configuration changes. Findings are mapped to the Essential Eight and SMB1001.
Live. Sign-up is open.
Four verdicts.
Every check returns one of these four verdicts.
- OK
OK
The check ran and found no gap.
- AT RISK
At risk
The scan found exploitable software, a missing control or an exposed service.
- NOT ASSESSED
Not assessed
The check did not complete. It does not count as a pass.
- NOT OBSERVABLE
Not observable
The control cannot be checked from outside your network.
What every scan checks.
Every scan runs these six checks.
Attack-surface discovery
Lists every exposed host and service. Remote-access and database ports are flagged.
Vulnerability checks
Checks the services you expose for known CVEs, misconfigurations, default logins and TLS problems.
Email authentication
Checks SPF and DMARC in DNS for missing records, softfail, p=none and broken policies.
Exploited-in-the-wild ranking
Ranks findings against CISA’s Known Exploited Vulnerabilities catalogue and EPSS scores.
Attack paths
When a gap matters, shows the route an attacker could take to reach it, as MITRE ATT&CK techniques.
Change tracking
Each scheduled scan is compared with the previous one and anything that gets worse is reported.
