Solutions // Cybersecurity Cybersecurity Cybersecurity for regulated organizations that need security operations to work in the real world. Sentinel Blue provides cybersecurity services for small and medium-sized businesses, defense contractors, government contractors, and regulated organizations, with a particular focus on the Defense Industrial Base. Our work spans security leadership, detection and response, vulnerability management, risk, compliance, Zero Trust, cloud security, and long-term security maturity. The goal is not to layer more tools onto your environment. It is to build and operate a security program that gives your team clear visibility, clear ownership, and a practical way to manage risk. For organizations subject to CMMC and other regulatory requirements, that distinction matters. Passing an assessment and operating a secure environment are related, but they are not the same thing. You need security practices that can stand up to scrutiny and still work day to day.

What Are Managed Cybersecurity Services?
Managed cybersecurity services give your organization ongoing access to security expertise, monitoring, technology, and operational support without requiring you to build every capability internally. That can include monitoring security alerts, investigating suspicious activity, managing vulnerabilities, developing security strategy, supporting compliance requirements, responding to incidents, and improving the maturity of your security program over time. The exact model depends on what your organization already has. A company with a capable IT team may need security leadership, threat monitoring, or specialized compliance expertise. Another may need broader operational support across several security functions. The key is that managed security should extend your team, not replace good internal ownership. No single platform, service, or security product makes an organization secure or compliant by itself.
Cybersecurity Services
Sentinel Blue's cybersecurity practice covers nine core service areas. Each can address a specific security need or work as part of a broader program.
Virtual CISO (vCISO) A virtual CISO gives your organization experienced security leadership without requiring a full-time executive hire. The work can include setting security priorities, reviewing risk, helping leadership make informed security decisions, and creating a practical roadmap for improving the program. A vCISO can also help connect technical security work with business, contractual, and compliance requirements so your team knows what needs attention first. Explore Virtual CISO Services →
Security Operations Center (SOCaaS) SOC as a Service provides ongoing security monitoring and analyst support without requiring you to build and staff a security operations center entirely in-house. SOC analysts review alerts, investigate activity, look for signs of compromise, and help determine which events require action. Sentinel Blue operates its own in-house Security Operations Center rather than outsourcing the function to a third party. Learn About Our SOC →
eXtended Detection and Response (XDR) XDR brings security telemetry from multiple parts of your environment together so suspicious activity can be investigated with more context. Instead of treating endpoint, identity, cloud, and other security signals as isolated events, XDR helps security teams correlate activity and investigate potential threats across systems. The technology is most effective when paired with analysts who understand what they are seeing and know when to escalate. Explore XDR Services →
Zero Trust Zero Trust is a security approach built around continually verifying users, devices, access, and context rather than assuming that activity inside a network can be trusted. A Zero Trust program can involve identity, access controls, segmentation, device security, monitoring, and policy. It is not a single product and it is not achieved by enabling one setting.

Microsoft Sentinel Microsoft Sentinel is Microsoft's cloud-based security information and event management platform. It can collect and analyze security data across an environment to help security teams identify, investigate, and respond to suspicious activity. Sentinel Blue supports Microsoft Sentinel as part of its GovCloud and cybersecurity practices. The platform provides security data and detection capabilities, while analysts and security processes determine how those signals are investigated and acted on. Explore Microsoft Sentinel Services →
Incident Response Incident response is the structured process of identifying, containing, investigating, and recovering from a cybersecurity incident. The work does not begin when an incident happens. Effective incident response also requires preparation, defined responsibilities, escalation procedures, and a clear understanding of what systems and data matter most to your organization. Learn About Incident Response →
Vulnerability Management Vulnerability management is the ongoing process of identifying security weaknesses, evaluating the risk they create, prioritizing remediation, and tracking them through resolution. A vulnerability scan is only one part of that process. The harder work is deciding which findings matter most in your environment and making sure remediation happens in a way your IT and security teams can sustain. Explore Vulnerability Management →
Risk Compliance & Assessments Risk and compliance assessments help you understand where your current security program stands against contractual, regulatory, and organizational requirements. For companies in the Defense Industrial Base, that often includes understanding how security controls, technical practices, policies, evidence, and day-to-day operations align with CMMC requirements. Sentinel Blue is a CMMC Third-Party Assessment Organization authorized by the Cyber AB, and its team includes CMMC Certified Assessors. Learn About Risk Compliance & Assessments →
Strategy & Maturity Security maturity work focuses on improving how your cybersecurity program operates over time, not simply completing a one-time project. That means identifying gaps, setting realistic priorities, defining ownership, improving processes, and building a roadmap that reflects your organization's risks and obligations. The result should be a program your team can operate and improve, not a binder that sits on a shelf. Explore Strategy & Maturity Services →
Why Sentinel Blue
Cybersecurity and compliance are often sold as separate problems. In regulated environments, they overlap constantly. Sentinel Blue is a CMMC Third-Party Assessment Organization authorized by the Cyber AB, and our team includes CMMC Certified Assessors. That gives our cybersecurity practice direct exposure to the requirements defense contractors are expected to meet and the evidence those programs need to produce. Our security operations capability is also operated in-house. Sentinel Blue runs its own Security Operations Center rather than passing monitoring and analysis to an outside provider. All Sentinel Blue personnel are U.S. persons operating from U.S. soil. The company is based in Warrenton, Virginia, and was founded in 2019. Sentinel Blue also operates a dedicated GovCloud practice supporting Microsoft 365, Azure Government, GCC High, and Microsoft Sentinel, along with Shield, its managed compliance and IT program. Those capabilities allow security operations, cloud architecture, compliance, and IT management to be treated as connected parts of the same environment rather than isolated projects. No credential, platform, or managed service removes the need for internal ownership. Our role is to give your organization the expertise, operating capability, and structure needed to make better security decisions and execute them consistently.

Frequently Asked Questions
What are managed cybersecurity services? Managed cybersecurity services provide ongoing security expertise and operational support to help your organization monitor threats, manage risk, respond to incidents, and improve its security program. The services can supplement an internal IT team or provide capabilities your organization does not maintain in-house. The exact scope depends on your environment, risk, regulatory obligations, and existing staff.
What is the difference between an MSSP and an in-house SOC? An MSSP is an outside provider that delivers security services to customers. A Security Operations Center is the team and operational environment responsible for monitoring, investigating, and responding to security activity. Some cybersecurity providers outsource their SOC operations to another company. Sentinel Blue operates its own in-house Security Operations Center rather than outsourcing monitoring to a third party.
Do I need a vCISO if I already have an IT director? Possibly. An IT director and a CISO solve different problems. IT leadership typically focuses on keeping systems, users, infrastructure, and technology operations running. A vCISO focuses on security risk, governance, security strategy, executive decision-making, and the long-term direction of the cybersecurity program. In many smaller organizations, the two roles need to work closely together.
What does Zero Trust mean? Zero Trust is a security model based on continually verifying access instead of assuming users or devices should be trusted because they are already inside the network. It typically involves identity, device security, access controls, segmentation, monitoring, and policy. Zero Trust is an architecture and operating approach, not a single tool or product.
Is Microsoft Sentinel the same as a SOC? No. Microsoft Sentinel is a security technology platform. A SOC is the team and operational function that monitors and investigates security activity. Sentinel can collect data, generate detections, and help analysts investigate threats. It still requires people, procedures, escalation paths, and response processes to turn those signals into effective security operations.
Does using a managed security provider make us CMMC compliant? No. A managed security provider can support parts of your cybersecurity and compliance program, but no single service creates CMMC compliance by itself. CMMC involves specific security requirements, documentation, evidence, technical practices, and organizational responsibilities. Sentinel Blue's status as an authorized C3PAO and the presence of CMMC Certified Assessors on its team give its cybersecurity practice direct experience with those requirements, but your organization still owns its compliance program.
