Quick Reference
- What is the difference between MSSP, MDR, and vCISO?
- MSSPs run broad security operations (SIEM, firewall, scanning). MDR providers specialize in 24/7 threat detection and active response on their own tech stack. A vCISO is fractional senior leadership for strategy, not operations.
- How much does it cost to outsource cybersecurity?
- MSSP retainers run $3,000 to $50,000+ per month. MDR is per-endpoint. vCISO retainers are $5,000 to $15,000 per month. Web app pen tests are $5,000 to $25,000. Red team engagements exceed $75,000.
- When should I hire an incident response retainer?
- Before you need it. Pre-paid retainers guarantee response-time SLAs and cap emergency rates. Engage a retainer once you handle regulated data, customer PII, or critical infrastructure.
- How long does a penetration test take?
- Web app pen tests typically take one to three weeks. External network tests two to four weeks. Red team engagements run four to twelve weeks. Reporting adds one to two weeks on top.
