The Level 4 service portfolio
Managed IT, Cybersecurity & Resilience Services
Choose the operating model that matches your team: complete IT and security ownership, co-managed protection for internal IT, or focused programs for disaster recovery, compliance, and secure AI adoption.
- Senior-led delivery
- 24/7 security operations
- Flexible ownership models
Managed security, clearly defined
Level 4 is a managed security service provider
A managed security service provider (MSSP)—also called a managed security services provider or managed security provider—operates ongoing cyber security services instead of simply selling security tools.
Level 4 connects 24/7 security monitoring, managed SOC and SIEM operations, EDR/MDR/XDR, identity and email protection, vulnerability management, compliance support, incident escalation, and recovery coordination. Cybersecurity is integrated with day-to-day IT through MSSP One or delivered alongside an internal team through MSSP Converge.

What a managed security provider should do →Five service models
Start with the outcome your organization needs
Each model connects to the same Level 4 engineering, security, compliance, cloud, and recovery capabilities. The difference is the responsibility Level 4 assumes and the business outcome the engagement is designed to support.
Fully managed IT & cybersecurity
MSSP One
One accountable Level 4 team takes primary responsibility for daily IT operations, user support, infrastructure, cybersecurity, cloud, compliance support, backup, and recovery.
Best for: Organizations that want to outsource operational ownership instead of coordinating separate IT and security vendors.
- Fully managed IT operations
- Security embedded in support
- One escalation and reporting model
Co-managed cybersecurity
MSSP Converge
A dedicated security layer that works alongside internal IT, adding 24/7 monitoring, senior escalation, compliance depth, incident coordination, and specialized engineering capacity.
Best for: Organizations with internal IT staff that need stronger security operations and expert coverage without surrendering day-to-day control.
- Works alongside internal IT
- 24/7 security operations
- Senior security and compliance depth
Managed resilience & recovery
MSSP DR
A managed disaster-recovery model built around immutable backups, documented recovery priorities, regular validation, response coordination, and practical business-continuity planning.
Best for: Organizations that cannot afford to discover backup or recovery gaps during a ransomware event, outage, or regional disruption.
- Immutable backup strategy
- Recovery testing and documentation
- Coordinated continuity planning
Managed compliance operations
MSSP Compliance
Assessments, technology-backed control operations, automated reporting, compliance-platform mapping, an updated client-specific ISMS, maintained audit records, remediation, consulting, and audit support.
Best for: Financial, legal, industrial, regulated, and contract-driven organizations that need compliance to operate as a maintained program rather than a last-minute project.
- Technology-backed controls and reporting
- Mapped audit records and maintained evidence
- Consulting, remediation, and audit support
AI consulting & secure artificial intelligence
MSSP AI
Security-first AI consulting that evaluates appropriate artificial intelligence use cases, protects organizational data, establishes governance, and connects responsible automation to measurable operating needs.
Best for: Organizations exploring AI assistants, workflow automation, or internal knowledge tools while managing privacy, access, security, and human oversight.
- AI and artificial intelligence readiness
- Data protection and governance
- Secure automation with human oversight
One portfolio, clear ownership
How the service models fit together
Level 4 can own the full technology environment, extend an internal team, or operate a focused program. Services can evolve as staffing, risk, compliance, and recovery requirements change.
MSSP One provides broad operational ownership through one accountable team.
MSSP Converge adds cybersecurity depth while your team retains daily control.
MSSP DR, Compliance, and AI concentrate specialized expertise around resilience, assurance, and responsible innovation.
