MDR ROI: the actual numbers behind the managed security investment.

Security budget conversations are difficult. Cybersecurity spending is an investment against events that may or may not occur — and the return on investment for prevention is, by definition, things that didn't happen. How do you calculate ROI on an avoided breach? Here's how the actual numbers work for a typical small or mid-sized business in the Tennessee Valley.

The cost of a breach: starting with the baseline

The IBM Cost of a Data Breach Report 2025 puts the global average breach cost at $4.44 million. For SMBs, actual costs are lower in absolute terms but often more severe relative to company size. A realistic breach cost estimate for a 50-person business with 100 endpoints might include:

• Incident response and forensics: $50,000–$150,000
• Business interruption and downtime (average 24 days at reduced capacity): $100,000–$500,000 depending on revenue
• Data recovery and system restoration: $25,000–$100,000
• Legal fees and regulatory response: $50,000–$200,000
• Customer notification and credit monitoring: $10,000–$50,000
• Regulatory fines (if HIPAA, PCI-DSS applicable): $10,000–$1,000,000+
• Reputational damage and customer loss: difficult to quantify, often the largest long-term cost

Conservative total: $250,000 to $1,000,000+ for a moderate-sized SMB. For healthcare or financial services businesses with regulatory exposure, significantly more.

Annual breach probability

For a 100-endpoint business without managed security, the annual probability of a significant breach event is not trivial. Verizon DBIR 2025 data suggests small businesses face a meaningful breach probability annually — with businesses in targeted sectors (healthcare, financial services, legal) facing higher exposure. Using a conservative estimate of 10% annual breach probability for an unprotected SMB:

Expected annual loss = breach probability × breach cost = 10% × $500,000 = $50,000/year in expected loss.

What MDR costs vs. what it saves

SignalPoint's MDR service for a 100-endpoint business costs a fraction of that expected loss. MDR provides:

• Elimination or dramatic reduction of breach probability (organizations with MDR experience significantly fewer catastrophic breaches)
• Reduction in cyber insurance premiums: 97.5% average reduction means a $50,000 annual premium might drop to $5,000–$15,000
• Elimination of internal security staffing costs: a single in-house security analyst costs $80,000–$120,000 in salary alone; MDR covers everything that analyst would do
• Elimination of security tooling costs: EDR, threat intelligence, and SIEM platforms included in MDR
• Faster incident response when breaches do occur: reduced breach cost for incidents that do happen

The actual ROI calculation

For a 100-endpoint business: MDR annual cost vs. expected annual loss reduction + insurance savings + avoided tooling costs. In most scenarios, MDR produces a positive ROI within the first year — before accounting for the avoided catastrophic scenario that would threaten business continuity. The question for most SMBs is not whether they can afford MDR. It's whether they can afford the breach they're likely to experience without it.
