By registering for both the Vulnerability Monitoring Service and SIEM integration, your public sector organisation benefits from continuous vulnerability scanning and threat alerts delivered directly into your existing security tools.
To make sure we’re monitoring your everything that could be targeted, you should share your zone files with our team. This lets us keep an eye on all your domains and subdomains, helping ensure nothing is missed and reducing the risk of vulnerabilities going unnoticed.
This powerful combination of services helps you:
- detect issues early
- fix problems faster and more efficiently
- monitor all your domains
- respond quickly to new vulnerabilities
