Our vCISO service delivers strategic security oversight, board and executive communication, risk management governance, and program direction tailored to your organization's size, industry, and risk appetite.
Prepare for audits and certifications with confidence across the industry's most critical frameworks.
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.
Fulfill the HIPAA Security Rule's mandatory Security Risk Assessment (SRA) requirement while gaining a clear picture of your ePHI risk landscape. 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.
The documentation, processes, and programs that form the operational backbone of a mature security function.
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.
Build the capability, plans, and team readiness to contain threats fast and recover with confidence.
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.
Real-world validation of your defenses — identify vulnerabilities before adversaries do.
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.
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.
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.
Detect, analyze, and respond to threats with visibility and speed across your 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.
Build purpose-built programs that address your organization's most complex and persistent security challenges.
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.
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.
