vCISO vs MSSP for a 100-Person Company: Which Is More Cost Effective in 2025?
For a 100-person company, a vCISO typically costs $2,000-$6,000 per month and provides strategic security leadership, policy development, and compliance guidance. An MSSP runs $5,000-$15,000 per month for operational monitoring and response. Most SMBs get better ROI from a vCISO unless 24/7 threat monitoring is a compliance requirement.
Can a vCISO replace an MSSP entirely for a 100-person company?
In many cases, yes. If your company does not have a regulatory requirement for 24/7 monitoring and has a competent IT team handling day-to-day security operations, a vCISO paired with a well-configured EDR and email security stack can deliver adequate protection at lower cost. However, if your cyber insurer mandates continuous monitoring or you operate in PCI DSS, CMMC, or HIPAA-regulated environments, you will likely need both.
What is the minimum budget a 100-person company should set aside for cybersecurity in 2025?
Industry benchmarks suggest SMBs should allocate 5-10% of their IT budget to security. For a 100-person company with a $500,000 IT budget, that implies $25,000-$50,000 per year. A vCISO-led program (retainer plus essential tools) can be structured to fit within that range. A full MSSP engagement typically exceeds the lower end of this range on its own.
How do I know if I need a vCISO, an MSSP, or both?
Start with two questions: Do you have a documented security program, written policies, and a clear owner for compliance decisions? If no, you need a vCISO first. Do you have a regulatory or contractual requirement for 24/7 threat monitoring or continuous log review? If yes, you need MSSP or MDR services. If both answers are yes, you need both. A security assessment can clarify which gap is most urgent.
What should a 100-person company look for in a vCISO contract?
Look for a clearly defined monthly hour commitment (not just 'fractional'), explicit deliverables (risk assessment, policy library, board report cadence), escalation procedures for incidents, and a month-to-month or short-term renewal option. Avoid contracts that do not specify deliverables or that lock you into 12+ months before a proof-of-value milestone.
Do MSSPs help with SOC 2 or ISO 27001 certification?
MSSPs can provide technical evidence and log data that auditors require, but they do not own the compliance program. Auditors expect to see policies, risk assessments, vendor management procedures, and documented governance - none of which an MSSP produces. Companies pursuing certification typically need a vCISO or compliance consultant to build the program, with MSSP data serving as supporting evidence.
Is a vCISO appropriate if we have never had any security program at all?
Yes, and this is one of the strongest use cases. A vCISO's first engagement at a security-immature company typically includes a baseline risk assessment, policy development, and a prioritized remediation roadmap. This foundational work creates the architecture that makes any subsequent MSSP or tool investment more effective. Starting with an MSSP before having a strategy in place is a common and costly mistake.
How does cyber insurance factor into the vCISO vs MSSP decision?
Cyber insurers increasingly require documented security controls, a named security owner, and - for higher coverage tiers - evidence of continuous monitoring. A vCISO can satisfy the 'named owner' and documented program requirements, which directly affects premium pricing. Some insurers discount premiums by 10-20% for companies with a vCISO engagement. MDR or MSSP monitoring may be required for coverage above certain revenue or data-volume thresholds.
