Where the data comes from
39,816 IT service providers are tracked as of 2026-09-22. Every field on a profile traces to one of the source families below, and every figure on the site is read from that record rather than written by hand.
Source families
- Owner claims
- What a company tells us about itself once it has verified an email address on its own domain. Carries the self-reported label until a second source confirms it.
- Human review
- Our own review of a record, usually triggered by a correction or a conflict between sources.
- Government registries
- State Secretary of State filings, SAM.gov, and SEC filings.
- Google Places for location, rating and review counts, and Google PageSpeed for site performance.
- Professional networks
- Public company pages for headcount, leadership roles and hiring activity.
- Our own crawl
- The company's own website: services, certifications, pricing pages, vendor mentions and site structure.
- Semrush
- Organic search visibility, keyword footprint and backlinks.
- DNS and security scans
- SPF, DKIM and DMARC records, TLS configuration and security headers.
- CISA KEV
- Known exploited vulnerabilities affecting technology we observe in use.
What we never publish
- ·Email addresses. Not contact addresses, not role addresses, not inferred ones.
- ·Personal phone numbers.
- ·Names of people who are not company leadership.
- ·Review bodies and reviewer names.
- ·Home addresses, when an owner asks us to remove one.
The three trust labels
- Claimed
- Someone with a verified email address on the company's own domain has taken ownership of the record.
- Verified data
- The value was confirmed by a source independent of the company itself, not only by the company's own statement.
- Registered entity
- The company was matched to a filing in a government business registry.
Getting something changed
Anyone can report a wrong value. We check it against the source that produced it, and the record carries the change with its date. Submit a correction.
People data is separate. If you are named on a record and want that removed, we remove it without asking you to justify the request. Request people data removal.
MSP Signal never publishes email addresses. How the score is calculated is on the methodology page.
