Recurring vulnerability scans identify security weaknesses in your network and infrastructure before attackers find them. Monthly or weekly scans detect newly published CVEs affecting your systems, catch misconfigurations introduced during routine changes and track which vulnerabilities have been patched and which remain exposed.
A one-time pentest gives you a snapshot of your security at a specific moment. Vulnerability scanning runs continuously as a complement, checking for new CVEs as they're published and verifying that patches actually get applied. This catches the gap between "we deployed the patch" and "the patch is actually running on all systems."
In order to comply with regulations such as ISO27001 or NIS2 recurring scans in needed to keep an inventory of current technical threats and risks. Shelltrail additionally adds the option to verify vulnerabilities before alarms are set off, meaning that only real threats is notified and security teams can focus on security, rather than false positives.
