Linux server hardening for fleets that can’t fail.
We turn fragile Linux fleets into resilient infrastructure—patched, monitored, and ready for audits—without disrupting product delivery.
72 hrs
Average hardening engagement
Baseline reviews, patching, and automation rolled out across fleets in three days.
0
Critical CVEs outstanding
All high/critical CVEs patched or mitigated with documented compensating controls by handover.
100%
Host logging coverage
Syslog, auditd, and metrics shipped to your SIEM/monitoring platform with alerting in place.
Where we focus
Security and reliability go hand-in-hand. We tackle the Linux gaps that expose your operations and compliance posture.
Unpatched kernels & packages
We implement patch automation, staged rollouts, and rollback plans across Debian, Ubuntu, RHEL, and Amazon Linux fleets.
Weak SSH & sudo hygiene
Enforce key-based access, MFA, privileged command logging, and role-based sudo policies.
Lack of telemetry & response readiness
Instrument auditd, process accounting, and host-based IDS, feeding dashboards that on-call responders can action in minutes.
Hardening playbook
A proven engagement flow that upgrades security posture while empowering your SRE/DevOps teams.
Phase 1
Discovery & baselining
Inventory packages, services, and users across hosts. Review cloud IAM roles, firewall rules, and CIS benchmark gaps.
Phase 2
Secure configuration
Apply hardened SSH configs, disable legacy services, enforce least privilege, and harden kernel/network parameters.
Phase 3
Automation & monitoring
Deploy Ansible/Terraform playbooks, configure logging to SIEM, add Falco/Wazuh/OSSEC if needed, and test incident response runbooks.
Deliverables by day three
- Hardened AMIs or base images ready for future autoscaling or VM provisioning.
- Automated patch pipelines with maintenance windows, slack notifications, and rollback plans.
- Security monitoring piped into your SIEM or a new lightweight stack (Grafana/Loki/Promtail, ELK, Datadog, etc.).
What you receive
Handover packages built for SRE, DevOps, and compliance teams to maintain hardened states.
Hardened baselines
Golden AMIs/VM templates or Ansible roles ready for future server provisioning.
Security policy pack
Documented SSH, sudo, firewall, and logging policies aligned with CIS/NIST recommendations.
Automation toolkit
IaC scripts, patch automation pipelines, and detection rules integrated with your tooling.
Operations training
Runbook walk-through and on-call training so teams can maintain hardened states confidently.
Frequently asked
We slot into your operations without slowing product velocity. Here’s how.
Do you support hybrid cloud?
Yes. We harden servers across AWS, Azure, GCP, on-prem VMware, and bare metal, aligning tooling and policies across environments.
Can you integrate with our existing configuration management?
We work with Ansible, Chef, Puppet, Salt, and Terraform. If you don’t have automation, we set it up with training included.
How do you avoid downtime?
We schedule rolling maintenance windows, use canary hosts, and include rollback procedures so production stays stable.
