Elite Offensive Cybersecurity & Regulatory Compliance Services
Objective, independent security validation engineered to expose vulnerabilities, satisfy federal compliance mandates, and protect operational continuity.
1. Network Security Assessment & Architecture Audit
Modern business infrastructure is no longer confined to a single office. With cloud migrations, hybrid workforces, IoT shop-floor devices, and legacy server environments, organizational perimeters have expanded exponentially. Network security cannot be managed through passive assumptions.
Keystone Cyber Division provides comprehensive network security assessments designed to uncover hidden exposure points across your entire technology stack. We begin by understanding your core business requirements and operational constraints, mapping your digital footprint, and systematically evaluating your defensive controls against modern attack frameworks.
Core Domains Systematically Evaluated
Perimeter & Network Defense
- ✓ Firewalls & Egress: Rule base optimization, stateful inspection, and outbound filtering.
- ✓ IDS / IPS Systems: Alert fidelity, signature tuning, and evasion testing.
- ✓ Zero Trust & Segmentation: Internal VLAN isolation and lateral boundary reviews.
- ✓ Secure Remote Access: MFA validation and VPN encryption enforcement.
Data & Infrastructure Governance
- ✓ Data Loss Prevention (DLP): Detection of unauthorized IP and CUI data exfiltration.
- ✓ Database Encryption: PKI infrastructure, at-rest/in-transit key management audits.
- ✓ Core Network Resiliency: Wireless security, DNS, DHCP, and IPAM resilience.
- ✓ Logging Architecture: Verifying critical telemetry is centralized and tamper-resistant.
2. Independent Penetration Testing & Adversary Emulation
Automated vulnerability scanners search for known software version banners; penetration testers prove real-world business impact. Our ethical hacking engagements simulate the exact tactics, techniques, and procedures (TTPs) deployed by advanced persistent threats and ransomware syndicates.
By chaining together minor configuration errors, privilege escalation paths, and human vulnerabilities, our certified red team demonstrates how an attacker could breach your perimeter, seize administrative credentials, or access critical financial and intellectual property databases. This proactive insight allows you to remediate real-world risks long before an actual breach occurs.
Offensive Testing Vectors
External Network Penetration Testing
Simulates an external threat actor on the public internet attempting to breach edge firewalls, remote access gateways (VPN, RDP), mail services, and cloud resources without authorized access.
Internal Network & Active Directory Auditing
Simulates a rogue insider or compromised contractor workstation. Tests lateral movement, privilege escalation, Kerberoasting, and Active Directory domain dominance to find privilege escalation paths.
Web Application Security (OWASP Top 10)
Deep-dive manual assessment of custom client portals, SaaS platforms, and APIs against SQL injection, broken authentication, IDOR, sensitive data leaks, and business logic flaws.
Social Engineering & Human Risk Simulation
Targeted spear-phishing campaigns, credential harvesting simulations, and security awareness metrics that train staff to recognize business email compromise (BEC) and invoice fraud.
Attack Chain Analysis & Proactive Threat Hunting
Attack Chain Analysis
- ✓ Intelligence Profiling & OSINT: Gathering exposed employee credentials and public intelligence.
- ✓ Active & Passive Recon: Mapping public attack surface and live service versions.
- ✓ Vulnerability Chaining: Combining minor weaknesses into critical entry vectors.
- ✓ Exploitation Proof: Safe privilege escalation proving tangible business risk.
- ✓ Covert Communication: Testing whether command-and-control traffic evades detection.
Proactive Threat Hunting
- ✓ Hypothesize: Formulating attack scenarios based on real-world threat intel.
- ✓ Investigate: Analyzing network logs, endpoints, and unusual authentication anomalies.
- ✓ Discover: Pinpointing dormant compromise indicators or unauthorized access points.
- ✓ Remediate: Delivering actionable technical fixes to eradicate root causes.
- ✓ Augment: Strengthening defensive telemetry to alert on future attempts.
Institutional & Federal Frameworks
- ✓ DoD CMMC 2.0 & NIST SP 800-171: Technical gap assessments and boundary validation for Northwest PA defense manufacturers handling Controlled Unclassified Information (CUI).
- ✓ FTC Safeguards Rule (16 CFR Part 314): Mandatory annual penetration testing and vulnerability assessments for automotive dealerships and CPA firms managing over 5,000 customer records.
- ✓ Cyber Insurance Underwriting: Independent technical attestation letters that satisfy carrier questionnaires and prevent policy denial or prohibitive rate spikes.
- ✓ HIPAA Security Rule: Technical vulnerability audits safeguarding electronic Protected Health Information (ePHI) from ransomware lockouts.
3. Cloud Security Consulting & Infrastructure Hardening
Cloud transformation accelerates business agility, but it fundamentally alters the security model. Traditional perimeter firewalls offer little protection against misconfigured cloud storage buckets, permissive Identity and Access Management (IAM) roles, or compromised API tokens.
Keystone Cyber Division designs and audits cloud security architectures that align directly with your operational goals. Whether you operate on Amazon Web Services (AWS), Microsoft Azure, Microsoft 365, or Google Cloud Platform (GCP), our specialists review your architecture to ensure least-privilege access, immutable backups, and continuous monitoring.
Cloud Practice Capabilities
Configuration & IAM Auditing
- ✓ CIS Benchmarks: Hardening against Center for Internet Security standards for AWS, Azure, and M365.
- ✓ Least-Privilege Enforcement: Eliminating over-permissive admin roles and orphan accounts.
Resilience & Architecture
- ✓ Secure Cloud Migration: Embedding defense from Day 1 to avoid costly refactoring.
- ✓ Ransomware Backups: Verifying air-gapped, immutable cloud repositories that ensure business recovery.
