We deliver cybersecurity services across four main practice areas. Each practice area is staffed by people who do that work specifically, not generalists who rotate across disciplines. The result is that when you engage us on a penetration test, a compliance program, or a SOC deployment, you are working with a team that has done that type of work many times before in environments similar to yours.
Our core cybersecurity practice covers the full assessment and protection lifecycle: security assessments and audits, vulnerability assessment, penetration testing, endpoint security, network security, threat detection and response, and AI security. We work both as a one-time engagement partner for specific assessments and as an ongoing security operations partner for organizations that need continuous coverage.
View ServicesFor organizations that need ongoing security operations support without building an internal team, we provide managed IT security, 24/7 SOC services, and cloud security management. Our managed services are designed to function as a direct extension of your team rather than as a black-box service that produces reports without context or engagement.
View Managed ServicesWe help organizations achieve and maintain compliance with the frameworks that apply to their industry and operations: GDPR, ISO 27001, HIPAA, PCI DSS, SOC 2, NIST CSF, and others. Our compliance work is integrated with our security work so organizations build programs that satisfy regulatory requirements and provide genuine protection rather than treating compliance as a documentation exercise separate from actual security.
View Compliance ServicesOur consulting practice provides IT strategy, security architecture advisory, and Virtual CISO services for organizations that need senior security leadership and strategic direction without the cost of a full-time CISO. vCISO engagements give organizations access to an experienced security leader who owns the security program, drives it forward, and reports directly to executive leadership and the board.
View Consulting ServicesThe way we approach security work is shaped by a few principles that affect how we scope engagements, what we focus on, and how we communicate findings. These are not marketing claims. They are the things that clients who have worked with other security firms most often say make us different in practice.
Understanding how attackers actually think and operate is the foundation of effective defense. Our team includes people who have spent significant time on the offensive side of security and who bring that perspective into every defensive engagement. We do not evaluate security programs based on whether controls are documented. We evaluate them based on whether those controls would stop an attacker who is actively trying to get past them.
Security teams are overwhelmed with findings, alerts, and recommendations. Our work is designed to cut through that noise and focus attention on the vulnerabilities that represent genuine risk to each client's specific environment, the alerts that signal real threats rather than normal activity variation, and the compliance gaps that carry actual regulatory exposure. We do not pad deliverables with low-risk findings that consume remediation capacity without reducing meaningful risk.
Security assessments and penetration tests that produce a report and nothing else have limited value. Findings that are not remediated do not improve security. We stay engaged through the remediation process, answer questions as your team works through fixes, validate that remediations have actually closed the gaps identified, and retest where necessary. The measure of a successful engagement is not the quality of the report. It is whether your security posture actually improved as a result.
Technical security findings need to reach technical teams in a form they can act on and executive leadership in a form they can use to make decisions. We produce deliverables that serve both audiences without requiring translation. Technical teams get specific, actionable remediation guidance with the context needed to prioritize their work. Leadership gets risk-framed summaries that connect security findings to business impact in terms that support resource and investment decisions.
We work across industries, but we have built specific expertise in sectors that face the most demanding combinations of threat exposure and regulatory obligation. Industry-specific knowledge changes what we focus on in assessments, how we design controls, and what we consider acceptable risk in a given operational context.
We work with hospitals, health systems, physician practices, health plans, and business associates to protect patient data, satisfy HIPAA and HITECH requirements, secure clinical IoT environments, and build ransomware response capabilities that account for the patient safety implications of system outages in clinical settings.
Learn MoreWe work with banks, credit unions, investment firms, insurance companies, and fintechs to protect against sophisticated financial fraud, ransomware targeting operational continuity, and AI-enabled attack techniques, while meeting the compliance requirements of PCI DSS, GLBA, DORA, and SOC 2.
Learn MoreWe work with federal agencies, state and local governments, municipalities, and defense contractors to address nation-state threats, ransomware targeting public services, and the specific compliance requirements of FISMA, NIST 800-53, CMMC, and StateRAMP within the budget and procurement constraints of public sector environments.
Learn MoreWe work with K-12 districts, colleges, and universities to defend against ransomware targeting academic operations, protect student data under FERPA and state student privacy laws, and build security programs that function within the open network environments and limited budgets that characterize educational institutions.
