Sentinel

Sentinel is the first entry point into the Let's Guard It! suite. It's an automated system that continuously inspects your online services, providing an up-to-date picture of their security. The system currently focuses on analyzing web services, which are currently the de facto standard for online services and mobile applications.

The context

Did you know that all online services are constantly under attack by botnets set up by cybercriminals, looking for vulnerabilities to exploit? A single vulnerability can be enough to cause your services and the data you manage to be compromised.

Verizon's most recent data breach report (Data Breach 2026) analyzed over 31,000 security incidents involving organizations in 145 countries, highlighting that, in the absence of operator errors or misuse of systems, the primary initial attack vector is the exploitation of security vulnerabilities. In 2025, organizations managed to remediate only 26% of critical vulnerabilities, which were actively exploited in the wild.

Even the simplest service is tempting for criminals as it can become part of their illegal infrastructure to exploit, typically for financial gain (e.g. selling the use of your systems or the exfiltrated data on the illegal market).

It is a good idea to be constantly updated on your vulnerabilities in order to promptly remedy them, before they are exploited illegally with much greater costs and economic consequences.

Sentinel is the solution

Any vulnerabilities are reported to you via automatic notifications, and you can view the details through a dedicated interface, with suggested mitigation measures prioritized based on the estimated threat. The threat assessment takes into account the presence of exploits, which are known programs or procedures capable of exploiting the identified vulnerabilities.

The plans

You can register a personal account on the platform completely free of charge to monitor your site using the Community plan. To view technical details on collected evidence and references to publicly available exploits, you can subscribe to the Professional plan. With the Business plan, your organization can also automatically collect results, so you can correlate and integrate Sentinel's analyses with those from other security systems (for example, a Security Information and Event Management - SIEM system) or ticketing systems to fix vulnerabilities.

Are your services critical to your organization or do they handle confidential data?
