On-Premises & Hybrid Infrastructure Hardening

On-premises infrastructure remains a critical attack surface for most enterprises. We review infrastructure security with adversary-minded assessment methodology.

What We Assess

Network Segmentation

Audit internal network routing, VLAN configurations, and routing tables.

Firewall Policy Review

Review active firewall rule lists and clean up legacy or open permissions.

Server OS Hardening

Check server OS settings against Center for Internet Security (CIS) benchmarks.

Active Directory Security

Audit AD domain controllers, trust relationships, group policies, and delegacy.

Patch Management

Assess server and workstation patch deployment scope, speed, and automation.

Endpoint Security

Verify coverage and policy enforcement of local antivirus and EDR agents.

Frequently Asked Questions

Answers to common questions for On-Premises & Hybrid Infrastructure Hardening.

Absolutely, because while the cloud is growing rapidly, hybrid environments remain the norm for most large organizations. We provide deep technical hardening for traditional data centers, physical servers, and legacy infrastructure that may not be cloud-ready. Our goal is to ensure that your on-premises defenses are just as robust and modern as your cloud-based ones.

We use the Center for Internet Security (CIS) benchmarks as the globally recognized gold standard for secure system configuration. We apply these rigorously tested settings to harden your operating systems, databases, and network devices against a wide range of attacks. Following these benchmarks ensures a consistent, high-level baseline of security across your entire infrastructure.

Active Directory is the most frequent target for ransomware and internal attacks, as it controls access to everything. We hunt for misconfigurations like weak Kerberos policies, excessive domain admin privileges, and dangerous attack paths using tools like BloodHound. Securing the keys to the kingdom is the most important part of any on-premises security strategy.

We review your patching cadence to ensure that critical vulnerabilities are addressed promptly and consistently across all systems. We also verify that your endpoint protection, such as EDR or antivirus, is properly deployed, updated, and actively blocking threats. Ensuring these foundational defenses are working correctly is your best defense against common malware and exploits.

We analyze your firewall rulebases to remove overly permissive or stale rules that are no longer needed for business operations. We also ensure that robust network segmentation is in place to isolate critical systems and prevent an attacker from moving laterally. This architectural defense is essential for containing a breach and protecting your most sensitive data.
