About Ntirety

Ntirety (formerly HOSTING, Inc.) has been delivering managed hosting and security services since 1997 and rebranded to Ntirety to reflect their evolution into a compliance-centric managed security provider. Their Compliant Security-as-a-Service (CompSaaS) model provides managed SIEM, MDR, compliance monitoring, and cloud security operations to healthcare, financial services, and government organizations with strict regulatory requirements. Ntirety's HITRUST CSF certification, PCI DSS compliance infrastructure, and HIPAA-compliant managed environments make them particularly well-suited for medical device companies, health systems, and financial institutions that require both continuous monitoring and formal compliance attestation. Their combination of managed cloud infrastructure and managed security services differentiates them from pure-play MSSPs by offering a fully integrated secure-by-design operating environment.

What Should You Ask When Evaluating Ntirety?

Before engaging any MSSP, use these questions to assess whether the provider is the right fit for your organization. These apply to Ntirety and any other provider on your shortlist.

What is included in the base service vs. what costs extra? Clarify whether incident response, compliance reporting, and additional log source onboarding are included or billed separately.
What response actions does the provider take directly? Some MSSPs only send alerts for your team to act on. Others take containment actions like host isolation or account lockout on your behalf.
What does the onboarding process look like? Ask about typical onboarding timelines, how much work your team needs to put in, and when full monitoring coverage goes live.
Can you provide references from similar organizations? Ask for references from companies in your industry and size segment. The experience of similar organizations is the best predictor of how the MSSP will perform for you.
What happens if we need to switch providers? Understand data portability, contract termination terms, and transition support. A transparent exit process is a sign of a provider that prioritizes long-term trust over lock-in.
