Patch Management
Do you have precise visibility into the vulnerabilities of your infrastructure? Are you certain that your patches are being applied correctly to all critical areas?
Mastering vulnerabilities, reducing the attack surface
Patch management strengthens the IT security of your infrastructure and reduces vulnerabilities across all your IT systems. We map your servers, workstations, and connected perimeters to accurately measure your security level and identify existing vulnerabilities. Integrating patching into the DevSecOps cycle secures CI/CD pipelines and prevents the introduction of vulnerabilities into production. Our IT security audits identify exploitable CVEs and produce a prioritized remediation plan based on risk analysis. Patch management governance formalizes a security policy and traceable security measures for the CIO and executive committee. We automate deployments and validation tests to ensure patches are applied and systems remain secure. Authentication controls and password management are integrated into processes to limit attack vectors. Rapid vulnerability remediation reduces exposure to cyberattacks and cybercrime campaigns targeting your services. Our technical recommendations cover encryption, cryptography, and network security measures to protect sensitive data. KPI-driven monitoring allows you to track your IT security level and justify the effectiveness of actions during an audit or an ANSSI review. We address legacy systems and non-patchable systems through compensatory measures to secure the system despite constraints. The solution includes SOC monitoring to detect security incidents related to missing or incorrectly applied patches. The strategy links risk management to operational playbooks to accelerate response in the event of an incident or exploit. Our rollback and testing procedures reduce the operational risk associated with large-scale updates on critical environments. We coordinate patching and encrypted backups to guarantee data continuity and security in the event of an incident. Server hardening measures and network segmentation reduce the scope of attacks and limit their impact on the IT system. Asset mapping identifies exposed systems and prioritizes patching based on business criticality. We include contractual controls and procedures for service providers to ensure their participation in security. Compliance with standards (NIS2, ISO, DORA) is facilitated by dashboards and audit evidence. Post-patch playbooks assess impacts and trigger corrective actions in the event of side effects or incidents. Our approach combines patch management, continuous monitoring, and tailored security solutions to protect information security. We train operational teams to reduce human error and improve the speed of patch application. Risk-driven prioritization transforms thousands of vulnerabilities into concrete and measurable actions to secure systems. Request a Patch Management Diagnostic to assess your security posture, prioritize patches, and protect your data.
Your major challenges
Patch management is often seen as "tactical" — but it is one of the most powerful pillars for containing cyber risks, required in the frameworks (ISO 27001, NIS2, DORA, SecNumCloud, SOC2…). It must be integrated into a strategy operational, controlled and automated vulnerability management.
Reduce the time of exposure to known vulnerabilities (critical CVEs, zero-days).
Strengthen the relationship between detected vulnerability and applied patch.
Obtain verifiable traceability for audits, post-incident analyses and compliance.
Integrate patching into the lifecycle of SOC, DevOps, Cloud, and IT.
Avoid “blind spots” on obsolete, legacy, third-party systems.
Frequent risks in the absence of a patching strategy
Critical CVEs have gone unaddressed for several months despite internal alerts
Critical environments (production, infrastructure, OT, cloud) outside of the classic patch cycle
Updates performed without validation/rollback possible → instability
SOC forced to urgently manage a breach that was nevertheless avoidable
Non-conformity revealed during a customer or supplier audit
