Continuous scanning of your external infrastructure to identify vulnerabilities before attackers do.
Find and fix vulnerabilities before an attacker does
60% of breaches are linked to poor patch management. Cyber-attackers constantly mass-scan the internet for known vulnerabilities that can be used to compromise organisations. Our vulnerability scanning features help you detect and remediate vulnerabilities in your infrastructure rapidly, checking against over 20,000 common entry routes and drastically reducing the opportunity for attack.
- Continuous assurance: Protect valuable infrastructure around the clock between pentests
- Complete customisation: Configure which security features are included for each target, and exclude any subdomains generating noise in your reports
- Simplified management: Pay one fee for all your security testing needs

Frequently Asked Questions

Vulnerability management is the ongoing process of identifying, assessing, and addressing security weaknesses in your external infrastructure before attackers exploit them.
60% of breaches are linked to vulnerabilities where patches were available but not applied. Regular vulnerability assessments help detect missing patches, misconfigurations, and weak points—significantly reducing your risk exposure.
Our system performs over 40,000 automated checks for outdated software, security misconfigurations, default passwords, and exploitable vulnerabilities across your configured external assets.
We monitor your internet-facing assets, including web applications, servers, network ports, cloud services, and external databases. If you’re unsure of your assets, we can identify them using Open Source Intelligence (OSINT) techniques.
Attackers frequently scan the internet for known vulnerabilities to exploit. By identifying and fixing your vulnerabilities proactively, you reduce the window of opportunity for attackers to compromise your systems.
With attackers scanning continuously, frequent assessments are crucial to minimize your risk window. Waiting 90 days between checks can leave your business exposed for long periods, as attackers can exploit weaknesses within minutes.
It not only highlights areas for improvement but also provides a detailed inventory of your exposed assets. Our platform rates each vulnerability with a CVSS score, helping you prioritise fixes based on risk severity.
Results are delivered immediately. The OnSecurity Portal notifies you as soon as vulnerabilities are discovered via in-portal alerts, SMS, or Slack integrations.
Yes. Many compliance standards such as PCI DSS and NHS DPS require vulnerability assessment reports. You can easily download detailed reports directly from the OnSecurity Portal for auditing and compliance purposes.
