We harden your servers and networks to recognized CIS benchmarks — firewalls and WAF, SSH lockdown, intrusion detection, patch management and audit logging — then keep watching so weaknesses get closed before anyone finds them.
Assessed, hardened, monitored and patched so attackers run out of surface to hit.
We baseline your systems with Lynis, OpenVAS and nmap, map every exposed service, and turn the findings into a prioritized, plain-English remediation plan.
OS and service configuration brought in line with CIS benchmarks — kernel parameters, file permissions, disabled defaults and least-privilege everywhere.
Default-deny firewalls with ufw/nftables and a tuned WAF in front of your apps — only the ports and paths you actually need stay open.
Key-only SSH, no root login, hardened ciphers, MFA where it fits, and tight access controls so remote entry stops being an easy door.
fail2ban or CrowdSec deployed and tuned to spot brute-force and probing traffic, then ban offenders automatically before they get anywhere.
Managed patch cadence for OS and packages, plus centralized, tamper-evident audit logs so you always know what changed and who did it.
We shrink your attack surface, benchmark every box, and keep the watch running — so a single missed setting never becomes the way in.
No — we harden in stages and test as we go. We baseline first, apply changes in a controlled way (staging where possible), and verify your apps still work at every step. Anything that could affect a service is flagged and agreed with you before it ships, so security tightens without surprise outages.
CIS benchmarks are consensus security configuration standards for operating systems and common services. We assess your systems against the relevant benchmark, then bring kernel settings, file permissions, account policies, network parameters and disabled default services into line — documenting each change and any deviations we agree to keep for operational reasons.
We deploy and tune an intrusion-detection layer — fail2ban or CrowdSec — that watches auth logs and traffic patterns, automatically bans IPs that hit failed-login or probing thresholds, and (with CrowdSec) shares reputation across a wider network. Combined with key-only SSH and a default-deny firewall, the easy automated attacks simply stop landing.
Both. We can do a one-off assessment and hardening pass as a Drop-In, or keep you on a monthly plan where we patch on a managed cadence, re-scan for new vulnerabilities, watch the audit logs and re-check your benchmark posture as your systems change.
