IT System and Infrastructure Configuration Review
Most security breaches result from misconfiguration, not zero-day exploits. Review according to CIS Benchmarks + best practices. You get a specific list to fix, not generalities.
What is an IT System and Infrastructure Configuration Review?
An IT System Configuration Review is a systematic comparison of your operating systems, databases, network devices, and cloud environments against CIS Benchmarks (700+ controls) to surface misconfigurations — such as default passwords, open ports, or over-permissive IAM roles — before attackers exploit them. nFlo combines automated CIS-CAT Pro scanning with expert manual review and delivers prioritized remediation recommendations plus a follow-up scan 30 days later to verify fixes; misconfiguration causes 30% of all security incidents.
Default password, open ports, old versions - recipe for incident

S3 Bucket Without Security = 3 Million Leaked Records
E-commerce company left public S3 bucket with 3 million customer records. Configuration? AWS default settings with one overlooked checkbox. Cost: €1.2M GDPR fines + class action lawsuits + reputation loss. Security researcher found bucket in 20 minutes through Google dorking.
Without systematic configuration review:
- Default passwords and credentials in production
- Open ports and services unnecessary for operation
- Outdated software versions with known CVEs
- Wrong permission configuration (too broad, no MFA)
We Don’t Guess - We Measure Against Standards
We compare your configuration with CIS Benchmarks (700+ security controls) and industry best practices. You get a specific “what to fix” list, not generalities like “improve security posture”.
What you get:
- Operating system review (Windows, Linux) according to CIS Benchmarks
- Database configuration audit (MS SQL, Oracle, MySQL, PostgreSQL)
- Network device review (firewalls, switches, routers)
- Cloud configuration verification (AWS, Azure, GCP)
- Hardening and unnecessary services analysis
- Password policies, MFA, privileged accounts verification
- Compliance report with % conformance for each control
- Prioritized recommendations (critical → high → medium → low)
- Automated remediation scripts where possible
- Follow-up scan after 30 days (verification of fixes)

Common questions about IT System and Infrastructure Configuration Review.
How long does the configuration review take and what is the deliverable?
The review takes 1-2 weeks depending on the number of systems. The deliverable is a report with deviations from CIS Benchmarks, prioritized recommendations (critical to low) and a hardening guide with automated remediation scripts.
What systems and platforms does the review cover?
We cover operating systems (Windows Server, Linux RHEL/Ubuntu/Debian), databases (MS SQL, Oracle, MySQL, PostgreSQL), network devices (Cisco, Fortinet) and cloud configurations (AWS, Azure, GCP).
Does the review require administrative access to our systems?
Yes, to perform CIS-CAT Pro scanning and manual review we need read-only access to system configurations. The scope of access is agreed during the inventory phase.
Do you verify the implementation of fixes after the review?
Yes, as part of the service we perform a follow-up scan 30 days after delivering the report to verify the effectiveness of implemented fixes and measure the improvement in % compliance with CIS Benchmarks.
