Frequently asked questions

Answers to the questions we hear most. Still unsure how it applies to your environment? Our engineers are happy to talk it through.

What's the difference between infrastructure hardening and a vulnerability assessment?
A vulnerability assessment identifies known software vulnerabilities through scanning. Infrastructure hardening reviews configuration settings against security baselines to remove unnecessary access and services. Both are valuable and complementary. Hardening reduces the attack surface. Vulnerability assessments find exploitable weaknesses in what remains.
Do you follow CIS Benchmarks for all platforms?
Yes, CIS Benchmarks are our default baseline standard. For regulated industries or specific compliance requirements, we can also align to NIST, DISA STIGs, or CCCS guidance.
Will hardening changes affect our production systems?
Some hardening recommendations carry operational risk and we flag these clearly. We recommend testing changes in a staging environment before applying them to production and can advise on the safest deployment sequence.
Can you harden our cloud infrastructure at the same time as on premises?
Yes. Many clients engage us for a combined cloud and on-premises hardening assessment. We scope these as a single engagement to give you a unified picture of your infrastructure security baseline.
How often should infrastructure hardening be reviewed?
At minimum annually, and after significant changes such as migrations, platform upgrades, or acquisitions. Configuration drift is ongoing, so periodic review is part of a mature security program.
