Network Vulnerability Assessment
NYCF's network vulnerability assessments examine both the internal and external attack surface of your organization. After remediation, many organizations follow up with penetration testing to verify that vulnerabilities have been closed and no exploitable paths remain. For critical infrastructure and industrial environments, our OT network assessment service applies specialized methodology that accounts for ICS constraints. External assessments take the perspective of a threat actor with no prior access, enumerating internet-facing hosts, services, and exposed management interfaces before probing each for exploitable conditions. Internal assessments evaluate the security of your network from the inside, identifying the vulnerabilities that would be available to an attacker who has already gained a foothold through phishing, a compromised credential, or a supply chain intrusion.
Network device configurations, including firewalls, switches, routers, and VPN concentrators, are reviewed against hardening benchmarks from CIS and NIST. Our analysts enumerate all open ports and running services across in-scope IP ranges, identify software versions, and cross-reference each against the National Vulnerability Database (NVD) to produce a patch gap analysis that reveals exactly where your systems are exposed. Active Directory environments receive particular attention: misconfigurations in AD are among the most exploited attack paths in modern intrusions, and NYCF examines privilege structures, Kerberos delegation settings, stale accounts, password policies, and group policy misconfigurations that attackers routinely chain together to move from a low-privilege foothold to domain-level control.
Wireless networks and remote access infrastructure round out the network assessment scope. Wi-Fi networks are tested for encryption weaknesses, rogue access point exposure, and network segmentation failures that allow wireless clients to reach sensitive internal systems. VPN configurations are reviewed for split-tunneling risks, certificate validation issues, and authentication weaknesses. Every finding receives a CVSS v3.1 score and is placed in a remediation priority matrix so your team knows exactly where to focus first.
Application and Web Vulnerability Assessment
Web applications and APIs represent one of the most actively targeted attack surfaces in the modern enterprise. NYCF's application vulnerability assessments follow the OWASP Testing Guide methodology and cover the full OWASP Top 10, including injection vulnerabilities, broken authentication, security misconfiguration, and insecure deserialization. Each identified vulnerability is manually verified by a certified analyst to confirm exploitability in your specific application context, eliminating the false positives that make generic scanner output unreliable as a basis for security decisions or legal proceedings.
Authentication and session management are examined in detail. Weak password policies, absent multi-factor authentication, predictable session tokens, session fixation vulnerabilities, and improper logout behavior are all assessed. Our analysts test input validation across every parameter in every application function, including parameters that automated tools frequently miss because they appear in non-standard locations such as JSON payloads, XML bodies, HTTP headers, and WebSocket messages. Business logic flaws, which scanners fundamentally cannot detect because they require understanding the application's intended behavior, are identified through manual analyst review.
For organizations operating mobile applications, NYCF's assessment extends to iOS and Android clients, examining insecure local data storage, improper certificate validation, insecure inter-process communication, and client-side security controls that can be bypassed. Cloud infrastructure supporting web applications receives a configuration review covering AWS, Azure, and GCP environments, with particular attention to S3 bucket permissions, IAM policy weaknesses, misconfigured security groups, and publicly exposed cloud storage containing sensitive data.
From Assessment to Attorney-Ready Report
The vulnerability reports that come out of automated scanner platforms are not suitable for legal proceedings, regulatory submissions, or informed executive decision-making. They contain false positives, theoretical vulnerabilities that are not actually exploitable in context, and findings presented without business impact context. NYCF's vulnerability assessment reports are fundamentally different because every finding has been manually verified by a certified analyst before it appears in the document.
Our reports are structured in two layers. The executive summary presents findings in plain language for attorneys, executives, and risk officers who need to understand the nature of the risk without reading technical details. It identifies the most critical vulnerabilities, articulates their potential business impact, and provides a high-level remediation roadmap prioritized by risk. The technical appendix provides full detail for IT and security staff: affected hosts, vulnerability proof-of-concept, exploitation complexity, and specific remediation steps including patch versions, configuration changes, and compensating controls where immediate patching is not feasible.
For organizations operating under specific regulatory frameworks, NYCF maps every finding to the applicable compliance requirement. This includes NIST Cybersecurity Framework functions and subcategories, PCI DSS requirements, HIPAA Security Rule safeguards, and NYDFS 23 NYCRR 500 sections. Organizations facing NYDFS examination, insurance underwriting assessments, or litigation arising from a security incident receive a report that is structured to support each of those specific purposes. When the matter involves active litigation or regulatory enforcement, NYCF maintains full chain-of-custody documentation for the assessment evidence and can provide expert witness testimony on the findings.
False-Positive-Free Findings
Every finding is manually verified by a certified analyst. No scanner output reaches the final report without expert confirmation of exploitability in your specific environment.
Litigation-Ready Documentation
Chain-of-custody preserved throughout. Reports are structured to support Daubert and Frye challenges, regulatory submissions, and insurance claims arising from security incidents.
Compliance Gap Mapping
Findings mapped to NIST CSF, PCI DSS, HIPAA, and NYDFS 23 NYCRR 500 requirements, supporting audit preparation and regulatory response.
Expert Witness Availability
NYCF's CCE and GIAC certified analysts are available to provide expert witness testimony on assessment findings in state and federal court proceedings.
