Turn Your Security Snapshot Into Practical Action Plans
Security tools often drown you in noise. This assessment is different. It gives you a clear, executive-friendly snapshot of your exposure so you can decide what to do next. Each report highlights critical vulnerabilities, known exploited weaknesses, risky email configurations like missing DKIM/DMARC, weak or outdated encryption, and exposed services that attackers actively target. You’ll see an overall weighted risk score, plus simple explanations written in plain English. Share it with your IT team or invite O and O Systems to walk through the findings and outline practical fixes that fit your budget and timeline. Use results to prioritize patches and show progress fast.
