Security Configuration
We harden servers, workstations, applications, and network devices following CIS benchmarks and each manufacturer's official recommendations.
Most incidents don't start with an exotic vulnerability but with default configurations that were never changed: standard passwords, unnecessary services left running, logging disabled, permissions that are too lax. Systematic hardening closes those doors that attackers' scanners find in seconds.
What's included
- Firewall, WAF, and IDS/IPS configuration according to network zone.
- Granular management of permissions, roles, and the principle of least privilege.
- Patches, updates, and a secure configuration baseline.
- Linux/Windows hardening according to CIS (Center for Internet Security) benchmarks.
- Web application hardening (headers, strict HTTPS, CORS, CSP).
- Centralized logging configuration for auditing and detection.
Ideal for
Companies that have just deployed new servers or applications and want to secure them before putting them into production, organizations undergoing external audits that need to pass controls, businesses that identified weaknesses in a pentest and need to fix them systematically, and any organization that wants to raise its security baseline.
How we work
We audit the current state against a benchmark (CIS, NIST, OWASP as appropriate), generate a deviation report prioritized by risk, and apply the changes in an orderly manner with functionality testing at every step. We document the standard configurations (golden images, Ansible playbooks) so that new systems are born hardened instead of having to be fixed afterward.
Frequently asked questions
Does hardening break applications?
If done without testing, yes. That's why we work in controlled windows, with staging environments that replicate production, and with rollback ready. Changes are applied incrementally, validating functionality at each step. In 2 years of experience, incidents caused by poorly applied hardening are rare and reversible.
What are CIS benchmarks?
These are guides published by the Center for Internet Security with secure configurations for operating systems, databases, browsers, cloud providers, and more. Each benchmark has hundreds of community-validated controls. They are the de facto standard for professional hardening and satisfy many ISO 27001 and PCI DSS requirements.
How often should configurations be reviewed?
We recommend a full annual review and partial reviews whenever there are major changes (new OS version, new application, topology change). Between reviews, continuous monitoring and automated patching maintain the baseline. Benchmarks are updated periodically and we keep up with them.
