Your security posture is only as strong as your weakest vendor. Our Third-Party / Supply Chain Risk Assessment evaluates the cybersecurity risks introduced by your vendors, suppliers, and technology partners — examining their security controls, data handling practices, contractual obligations, and access to your environment. We help you understand and quantify the risk your third parties pose, prioritize vendors by criticality and risk level, and build or mature a sustainable third-party risk management (TPRM) program that scales with your business.
Evaluate your cybersecurity program against the NIST Cybersecurity Framework's five core functions — Identify, Protect, Detect, Respond, and Recover. We assess your current maturity across all framework categories, benchmark you against industry peers, and deliver a prioritized improvement roadmap aligned to your risk tolerance.
Measure your organization's readiness for ISO/IEC 27001 certification. We evaluate your information security management system (ISMS) against all Annex A controls, identify gaps between your current state and certification requirements, and provide a structured remediation roadmap to accelerate your path to certification.
Prepare for your SOC 2 Type I or Type II audit with confidence. We assess your controls against the Trust Services Criteria — Security, Availability, Confidentiality, Processing Integrity, and Privacy — identify control gaps and design deficiencies, and help you remediate before your auditor arrives.
Assess your compliance posture against the Payment Card Industry Data Security Standard. We evaluate your cardholder data environment (CDE), scoping, and controls across all PCI DSS requirements, identify compliance gaps, and provide detailed remediation guidance to prepare your organization for formal QSA assessment.

We systematically identify threats and vulnerabilities to the confidentiality, integrity, and availability of electronic protected health information and provide a risk-prioritized remediation plan.
Evaluate your readiness for Cybersecurity Maturity Model Certification (CMMC) compliance — a requirement for all DoD contractors handling Federal Contract Information (FCI) or Controlled Unclassified Information (CUI). We assess your practices against your required CMMC level, identify gaps, and prepare you for a successful C3PAO assessment.
Assess your implementation of the CIS Critical Security Controls — a prioritized, prescriptive set of safeguards proven to defend against the most prevalent cyber attacks. We evaluate your coverage across all 18 CIS Controls and Implementation Groups, identify quick wins and strategic improvements, and provide a clear action plan to measurably reduce your cyber risk.
We develop a structured, repeatable patch management program that defines how your organization identifies, prioritizes, tests, and deploys security patches across all systems. A well-executed patching program is one of the most effective ways to close known vulnerabilities before attackers can exploit them.
We design and implement a comprehensive, risk-driven vulnerability management program that goes beyond periodic scanning. Our approach establishes a continuous lifecycle for identifying, assessing, prioritizing, remediating, and verifying vulnerabilities across your entire attack surface — integrating people, processes, and technology into a sustainable, measurable program.
Clear, enforceable security documentation is the backbone of any mature security program. We develop tailored security policies, standards, guidelines, standard operating procedures (SOPs), and operational runbooks that ensure your team follows consistent, auditable processes — and that auditors have exactly what they need to see. Security starts with policy.
Build or mature a robust incident response capability before an incident strikes. We develop comprehensive IR plans, scenario-specific playbooks, RACI matrices, communication templates, and escalation procedures — giving your team a clear, tested framework to follow when seconds matter most.
Stress-test your incident response plan through expertly facilitated simulation exercises. Our tabletop exercises present realistic attack scenarios — ransomware, data breaches, insider threats, supply chain compromises — and guide your leadership and response teams through decision-making and escalation in a no-stakes environment that builds real-world readiness.
Equip your security and IT teams with the knowledge, tools, and techniques needed to respond effectively when incidents occur. Our hands-on workshops cover incident classification, triage, digital forensics fundamentals, evidence preservation, threat containment, eradication, and recovery — turning theory into practice through scenario-driven exercises.
Evaluate your organization's ability to withstand, respond to, and recover from a ransomware attack — before one happens. Our assessment examines your prevention controls, detection capabilities, backup integrity, network segmentation, identity hygiene, and recovery procedures against real-world ransomware tactics. We deliver a prioritized roadmap that closes the gaps most likely to result in prolonged downtime, data loss, or extortion payments.
Our ethical hackers simulate real-world cyberattacks against your network, applications, and systems to uncover exploitable vulnerabilities before adversaries do. We offer network, web application, cloud, and social engineering penetration tests — each delivering detailed findings, risk ratings, and remediation guidance grounded in the tactics and techniques of real threat actors. Network penetration test engagements can be scoped as internal, external, or combined internal + external: an internal network pentest simulates a threat actor who has already gained a foothold inside your environment, uncovering lateral movement paths, privilege escalation opportunities, and weaknesses in internal controls; an external network pentest targets your internet-facing assets to identify vulnerabilities exploitable by an outside attacker before they can breach the perimeter; and a combined internal + external engagement provides the most comprehensive coverage, mapping the full attack chain from initial perimeter breach through to internal compromise and data exfiltration.
Purpose-built for the unique attack surface of web applications, our Web Application Penetration Testing service goes beyond automated scanning to simulate the manual, creative techniques real attackers use. Our testers assess your application against the OWASP Top 10 and beyond — probing for authentication flaws, authorization bypasses, injection vulnerabilities, business logic abuse, API weaknesses, and session management issues. Engagements are available as black-box, gray-box, or white-box assessments, and deliver detailed findings with proof-of-concept evidence, risk ratings, and developer-friendly remediation guidance.
Cyber threats don't stop at the digital perimeter. We assess the physical security controls protecting your facilities, data centers, and sensitive assets — evaluating access control systems, surveillance, badge protocols, visitor management, and physical intrusion resistance — to ensure your physical and cyber programs work in concert.
Your people are both your greatest asset and your most targeted attack surface. We conduct controlled, realistic phishing simulations — including email, smishing, and vishing campaigns — to measure employee susceptibility, identify high-risk individuals and departments, and provide targeted training recommendations that meaningfully reduce social engineering risk.
You cannot protect what you don't know exists. Our Network Mapping & Asset Discovery service provides a comprehensive, authoritative inventory of every device, system, and service present on your network — including shadow IT, unmanaged endpoints, and forgotten infrastructure. From a cybersecurity perspective, a complete and accurate asset inventory is foundational to every downstream security function: vulnerability management, patch prioritization, attack surface reduction, and incident response all depend on knowing exactly what is in your environment. Uncharted assets are prime targets — attackers actively seek out unmanaged and unmonitored systems that fall outside the scope of your security controls. From an IT governance perspective, asset discovery directly supports configuration management, software licensing compliance, capacity planning, and audit readiness. Regulatory frameworks including NIST CSF, CIS Controls, ISO 27001, and PCI DSS all require organizations to maintain an accurate inventory of hardware and software assets as a foundational control — making this engagement both a security imperative and a governance requirement.
Gain comprehensive visibility into the vulnerabilities present across your IT environment. Our vulnerability assessments leverage industry-leading scanning tools and expert analyst review to identify, classify, and prioritize security weaknesses — giving you a clear picture of your risk exposure and a prioritized roadmap to remediation.
Identify security vulnerabilities in your applications at every stage of the development lifecycle — from source code to running production systems. Our SAST/DAST service combines two complementary analysis techniques to deliver the broadest possible coverage of your application's attack surface.
Static Application Security Testing (SAST) analyzes your application's source code, bytecode, or binaries without executing the program — finding vulnerabilities at their root in the codebase itself. SAST is performed early in the development lifecycle (shift-left), enabling developers to discover and fix issues like hardcoded secrets, insecure functions, injection flaws, and misconfigurations before code ever reaches production. Because it examines the code directly, SAST provides deep visibility into the internal logic of an application and can pinpoint the exact file and line where a vulnerability exists.
Dynamic Application Security Testing (DAST) tests the application from the outside while it is running — simulating how an attacker would interact with the live system without access to source code. DAST uncovers runtime vulnerabilities that only manifest during execution, such as authentication weaknesses, session management flaws, misconfigurations, and server-side issues that static analysis cannot detect. Because DAST operates against a live environment, it reflects the real-world risk of your deployed application.
Together, SAST and DAST provide defense-in-depth for application security: SAST catches vulnerabilities early and deep within the code; DAST validates what is actually exploitable in the running application. Our engagements deliver prioritized findings, risk ratings, and developer-friendly remediation guidance mapped to OWASP and CWE standards.
As organizations deploy Unmanned Aircraft Systems (UAS) for facility inspection, site security, and operational monitoring, drones have become sophisticated "flying IoT" endpoints that traditional security tools are not designed to evaluate. Our UAS Cybersecurity Assessment covers four primary attack vectors: the aircraft — firmware integrity, physical port security, and sensor spoofing (GPS/IMU); communication links — encryption of the Command & Control (C2) link and video/telemetry downlink; Ground Control Station (GCS) — security and patch posture of the tablets, laptops, and controllers used to operate the drone; and cloud and backend infrastructure — storage of flight logs and captured data, API security, and third-party data sharing. Additional risks include drones as network entry points for lateral movement, sensitive data exfiltration (4K video, thermal, LIDAR), shadow IoT from unmanaged employee-operated drones, and external "war-flying" attacks targeting your wireless environment.
When malicious code is discovered in your environment, understanding precisely what it does is critical to an effective response. Our analysts perform static and dynamic malware analysis to reverse-engineer malicious software, extract indicators of compromise (IOCs), determine the full scope of impact, and provide actionable intelligence to accelerate containment and strengthen defenses.
You can't defend what you can't see. We design and deploy comprehensive security monitoring architectures — including SIEM platforms, log aggregation, alert tuning, and detection rule development — to provide continuous visibility into your environment and enable rapid detection and response to emerging threats.
Endpoints are the most targeted entry point in any organization. We help you select, deploy, and operationalize Endpoint Detection & Response solutions that provide deep visibility into endpoint activity, detect malicious behavior in real time, and enable rapid investigation and containment — ensuring your endpoints are defended long after the perimeter is breached.
Insider threats — whether malicious, negligent, or compromised — represent one of the most difficult risks to detect and manage. We help organizations design and implement comprehensive insider threat programs combining technical controls, behavioral analytics, policy frameworks, and response procedures to detect, deter, and respond to threats from within — while respecting privacy and legal boundaries.
Technology alone cannot protect your organization — your people must be an active part of your security defense. We design engaging, role-based security awareness programs that go beyond annual checkbox training, using behavioral science principles to drive lasting behavior change and cultivate a security-first culture at every level of your organization. We deliver security awareness training virtually or live, tailored to your team's schedule and learning environment.
Identify and address security risks during design — not after deployment. Our threat modeling workshops guide your engineering and security teams through structured analysis of systems, applications, and architectures to systematically identify threat actors, attack vectors, and potential vulnerabilities early in the development lifecycle, where fixes are most cost-effective and impactful.
