Practical security for organizations that can’t afford to get it wrong.

KleinSec helps small and mid-sized teams find real risks, fix what matters, and respond fast when something goes wrong.

Services

Security assessments: A hands-on review of your systems, cloud tenants, and configurations, from Microsoft 365 and Azure to email authentication, with a prioritized fix list written for both engineers and leadership.
Compliance audits: Find out where you stand against CIS Benchmarks, NIST CSF, or your customers' security questionnaires, and get a plain-language plan to close the gaps.
Code review and static analysis: Automated and manual review of your source code, scripts, and infrastructure-as-code to catch vulnerabilities before they reach production.
Vendor and solution review: An independent security review before you sign: gaps, compliance risks, and overbuilt scope, so you buy what you need rather than what you're sold.
Linux and endpoint hardening: Encryption, identity, policy, and certificate-based access for your fleet, automated so it keeps running without an expensive vendor contract.

Scope. We agree in writing on what's in scope, the timeline, and the cost before any work starts.
Assess. We do the work with minimal disruption to your team.
Report. You get plain-language findings ranked by risk, with clear fixes, written for both engineers and leadership.
Follow through. We confirm each fix is in place, or help you build it.
