We harden Linux and Windows and secure servers (web, database, app) with CIS and STIG baselines, Zero Trust and least privilege. We automate with Ansible/Terraform and manage config via GitOps to kill drift. We enforce SSH/TLS (TLS 1.2+/FIPS), tune the kernel (sysctl), enable SELinux/AppArmor, protect secrets and keys (KMS/HSM) and deploy FIM with auditd. Patching and CVE mitigations hit low MTTR, integrated with EDR. Our SRE approach honors security/availability SLOs, the error budget and safe change cycles.
Auditable baselines (CIS level 1/2, STIG) with comparable reports and evidence.
Near real-time drift control and self-healing without human touch.
We cover OS (RHEL/AlmaLinux, Ubuntu/Debian, SUSE; Windows Server), web (Nginx/Apache/IIS), databases (MySQL, PostgreSQL, SQL Server), middleware (Java/PHP/.NET), SSH/RDP, directory services and VM templates/cloud images. We harden Kubernetes nodes and containers (minimal capabilities, non-root users, read-only root, seccomp, AppArmor). We publish golden images, orchestrate patches by risk and enforce checklists with documented exceptions.
Compliance telemetry: host/role percentage (CIS L1/L2), critical controls (secure boot, logging, encrypted transport), FIM on sensitive files, auditd events (auth, privilege changes), crypto posture (TLS ciphers/KEX), port exposure, users/sudo and MTTR by CVE severity. We forecast backlog and team capacity to target the biggest attack surface reducers first.
Impact-based alerts: failed root logins, unexpected SUID/SGID, altered shadow, services listening on 0.0.0.0, unauthorized new admins, loaded kernel modules, SELinux/AppArmor disabled, weak ciphers and persistent drift. Every alert links to runbooks and clear escalation.
Incident response
P1
Root compromise or ransomware. Host isolation, key revocation, credential rotation, safe restore and continuous comms.
P2
Dangerous drift or suspected lateral movement. Reapply baseline, close ports, harden policies and increase monitoring.
Post-mortem
Blameless analysis, actionable lessons, hardening/patching improvements and permanent preventive controls.
We log affected security SLIs/SLOs, real detect/contain/recover timings and prevention tasks.
Self-healing
Automatic baseline re-apply via Ansible and rollback of unsafe changes.
Account disablement and key/cert rotation on exposure detection.
Host quarantine by NAC/tags and restore to known-good configs.
We minimize exposure time while keeping human control at key milestones.
Risk-based (CVSS + exposure) prioritization, maintenance windows, blue/green to reduce risk and MTTR metrics by severity. Temporary mitigations when no patch exists.
Granular roles, sudoers control and Privileged Access Management. PAM modules (lockout, password policy) and duty segregation with just-in-time access.
Golden images with cloud-init, agents and preapplied policies. Versioned, signed and scanned before rollout on-prem and cloud for fleet-wide consistency.

Summary
We cut the attack surface, speed up audits and keep consistency with automated baselines. With orchestrated patching, strong crypto, minimal exposure and drift control, your systems resist threats and meet compliance without slowing the business.
