About Incident Response providers
Teams that contain, investigate and recover from cyberattacks and breaches.
Cybersecurity companies protect organisations from attacks, data breaches and compliance failures through testing, monitoring, response and advisory work. Credentials, response capability and honesty about risk matter most.
In the United States, Incident Response Companies are concentrated around New York, San Francisco, Los Angeles, Austin, Chicago and Miami. Local rates sit at the upper end of the global ranges, so many buyers in the United States pair a local lead with nearshore or offshore delivery to manage cost.
How to choose the best Incident Response Companies in 2026-2027
- Agree a retainer before an incident happens.
- Ask for certifications such as CREST, OSCP, CISSP or ISO 27001.
- Check 24/7 monitoring and incident response capability.
- Ask how findings are reported and prioritised.
What does it cost?
Penetration tests commonly cost $5,000-$30,000 per scope; managed security (SOC/MDR) often runs $3,000-$20,000+ per month depending on size.
Before you sign
Ask for a written proposal with scope, milestones, team members and exit terms, and speak to at least one current client of each shortlisted provider.

How this list is compiled
Worldwide view: Clutch-verified specialists (registered businesses independently verified on Clutch with a working website, ordered by their number of verified client reviews) followed by established industry leaders. Country view: the main list is strictly local. It shows only Clutch-verified firms with an office in the selected country and established firms based in that country that the iCreativez research team selected for their scale and track record. Large international firms and remote teams that serve the country appear in a separate, labelled section and are never counted as local. Where we have not yet verified enough local firms, the page says so instead of padding the list. Minimum project size, hourly rates and team size are as published by each company in November 2026. Inclusion is free and not paid for. Providers can request a review via our contact page.
