Quarterly Vulnerability Assessments
Comprehensive, scheduled scans across all digital infrastructure to catch newly discovered CVEs, misconfigurations, missing security patches, and weak cipher suites before they can be leveraged by attackers.
VAPT
Vulnerability Assessment & Penetration Testing
Crimson Security provides rigorous, objective security assessments designed to uncover exploitable flaws, test operational defenses, and harden corporate infrastructure before adversaries strike. Combining automated intelligence with expert-led adversary simulation, our VAPT services give enterprise leaders complete visibility into their security posture.
Strategic Testing Cadence
Continuous assurance
Cyber threats evolve continuously, and perimeter configurations shift with every release and deployment. To maintain robust cyber hygiene and satisfy regulatory and cyber insurance mandates, Crimson Security recommends a dual-track security cadence.
Annual Penetration Testing (Internal & External Nodes)
In-depth, manual adversary simulations conducted at least once per year (or following major architectural overhauls) to validate whether identified vulnerabilities can be chained together to breach perimeter controls or compromise core assets.
External vs. Internal
Both sides of the firewall
A complete penetration testing program evaluates an organization from both sides of the firewall. Understanding the distinction between external and internal nodes is essential to evaluating risk realistically.
1. External Nodes Penetration Testing
Perimeter Defense
What it simulates
An external adversary attempting to breach your network from the public internet with zero insider knowledge or credentials.
Target nodes
Public-facing assets including corporate firewalls, VPN endpoints, web applications, customer portals, DNS servers, cloud perimeter services (AWS, Azure, GCP), and mail transfer agents.
Core objectives
- Identify perimeter misconfigurations, exposed management ports, unpatched software, and weak authentication controls.
- Attempt initial compromise, credential harvesting, or remote code execution from outside the enterprise border.
- Verify that perimeter defenses (e.g., WAFs, IDS/IPS, edge routers) detect and actively drop malicious ingress traffic.
2. Internal Nodes Penetration Testing
Zero-Trust & Blast Radius
What it simulates
A threat actor who has already bypassed perimeter defenses, such as through a successful phishing attack, supply chain compromise, rogue insider, or stolen remote-access credentials.
Target nodes
Assets residing within the private corporate network, including Active Directory/domain controllers, employee workstations, internal databases, local file shares, intranet applications, and industrial or IoT hardware.
Core objectives
- Test network segmentation and determine whether an infected host can freely move laterally across VLANs.
- Evaluate privilege escalation pathways (e.g., abusing Kerberos tickets, local administrator password reuse, unconstrained delegation).
- Determine how deeply an attacker can penetrate toward "crown-jewel" assets before internal detection tooling (EDR, NDR, SIEM) flags the activity.
Service Overview
Vulnerability Assessment vs. Penetration Testing
| Dimension | Vulnerability Assessment (VA) | Penetration Testing (PT) |
|---|---|---|
| Primary Goal | Catalog, prioritize, and report known system vulnerabilities. | Exploit identified weaknesses to demonstrate real-world business impact. |
| Execution | Automated and semi-automated diagnostic scanning with expert verification. | Manual, offensive adversary emulation using bespoke tools and tactics. |
| Scope | Broad scan across all internal and external network nodes. | Targeted deep dive into exploitable attack chains and high-value targets. |
| Recommended Frequency | Quarterly (plus continuous post-patch scanning). | Annually (or following significant infrastructure migrations). |
| Primary Deliverable | Prioritized remediation list organized by CVSS severity. | Full narrative report detailing attack paths, proof-of-concept exploits, and strategic fixes. |
The Crimson Methodology
Built on recognized frameworks
Our offensive security team operates under globally recognized industry frameworks, including PTES (Penetration Testing Execution Standard), OWASP, and NIST SP 800-115.
01
Reconnaissance & OSINT
Passive and active asset discovery, mapped across attack surfaces.
02
Threat Modeling & Vulnerability Analysis
Pinpointing exploitable vectors across system architectures and identity providers.
03
Exploitation & Lateral Movement
Safe, controlled ethical exploitation to confirm theoretical risk without causing operational disruption.
04
Post-Exploitation & Impact Scoping
Quantifying the blast radius by discovering what sensitive data or systems could be exposed.
05
Executive & Technical Reporting
Delivering two clear deliverables: an executive summary for leadership and board reporting, alongside detailed remediation blueprints for system administrators.
06
Remediation Validation
Complimentary re-testing of identified findings to verify that corrective patches and hardening measures were successfully applied.
