We make sure the only people who can reach your systems are the ones who should. We check your firewall posture, keep your network properly divided, and watch continuously so nothing quietly drifts out of shape. (Technically: zero-trust architecture, firewall management, IDS/IPS, and segmentation testing.)
Four phases. The first month gets you to a solid baseline. The program after that keeps you ahead of it.
We map what you have and where the risk really is. Two weeks to a clear, written baseline.
Start with a scope callWe fix the quick wins right away and run the first pen test in parallel. Your SOC onboarding starts.
Monitoring goes live, incident response is on call, and you get a plain-language report every week.
Retests, rehearsals, and rolling compliance evidence keep you ahead, not just caught up.
Every capability below is delivered as part of one managed program, scoped to your business, executed by our partner network, and managed by your Katalor Security lead. One contract, one point of contact, one report.
Configuration review and continuous monitoring of your firewall rule base. Rule-sprawl audit, change-control workflow, and drift detection between intended and deployed policy.
Signature-based and behavior-based intrusion detection on your network perimeter and internal segments. Tuned to your environment, not a shipped default ruleset, with alerts routed to the SOC.
Validates that your segmentation actually segments. Tests east-west reachability between zones, dormant routes, and forgotten any-any rules. The gaps that show up in tabletop scenarios.
Posture-based admission control for managed and BYOD devices. Quarantines unknown endpoints, enforces patch and EDR baselines before granting network access.
AD hygiene audit: privileged-account sprawl, stale objects, GPO drift, Kerberos misconfigurations. Catches the conditions that turn a phishing click into a domain takeover.
End-to-end assessment of network architecture, controls, and monitoring. Identifies the gaps between what the diagram shows and what the topology actually allows.
Pulse Check covers the basics: external network scan, firewall posture spot-check, basic segmentation review. The Monthly managed adds continuous firewall change monitoring and quarterly network segmentation testing.
