Headquartered in United KingdomHeadquarters countrySourced only from this vendor's own published headquarters address (schema.org structured data on their site) — never guessed from domain TLD. Source ↗

Do you work at Mimecast?

This profile was built from public sources and hasn't been claimed yet. Claiming it lets you correct what's wrong and add details only you can confirm — and marks that information as vendor-verified for buyers.

Free, and it does not affect ranking, placement, or comparison results. The first person verified on Mimecast's email domain becomes the profile admin.

Trust profileHow to read thisFive separate questions a buyer actually asks, each answered with its own evidence and a link to the source. There is deliberately no overall score: a single number invites comparison it cannot support, and would mostly reflect how much of Mimecast we have managed to scan rather than anything about the vendor.

Not checked means we have not looked yet, and is never counted against a vendor. Limited means we did look, but found only one line of evidence — enough to report, not enough to corroborate.

Data coverage: 32/100What this measures (and doesn't)

Not a quality rating or endorsement — a measure of how much verified, disclosed data we actually have about this vendor. A low score usually means "we don't have much verified information yet," not "this is a bad vendor." Never used to sort or rank vendor lists.

The platform admin controls the formula's weights.

Data coverage profileHow to read thisThe same four components behind the data coverage score above, shaped instead of listed — a vendor strong on verification but thin on buyer feedback looks visibly different from one that's the other way around. Security and feedback plot at the neutral midpoint (50) when there's no data yet (no products tracked, no reviews), matching how the actual score itself treats missing data — not a guess either way.

IntegrationsUI-12 — integration graphDetected from this vendor's own published integration/partner pages by the enrichment loop — each entry links the exact page it was found on. Directional: "integrates with" is claimed by this vendor; "integrated by" is claimed by the other vendor's site. Coverage grows as the scan progresses.

Buyer reviewsUI-14 — verified-buyer reviewsWritten only by domain-verified buyers at other companies, attributed to their company domain (never their identity), and moderated. Buyer-sourced opinion, clearly separate from the neutral catalog facts above — and never an input to search or comparison ordering.

No buyer reviews yet.

Reputation ratingUI-20 — anonymous ratingA single anonymous 5-star signal from buyers, resellers, and analysts who've engaged with this vendor — separate from the domain-attributed reviews above. No rater identity is ever shown, not even at company level.

External ratingsUI-22 — third-party ratingsAggregate rating and review count pulled directly from the source site's own published data — never the review text itself, which belongs to that site. Links go to the real page so you can read the actual reviews there.

Security & trust signalsAbout these signalsCertifications are keyword-matched from the vendor's own public pages (each claim links to its source — verify directly before relying on it). Security headers are checked live against the vendor's homepage, re-checked every 90 days. Both are independent, automated signals, not a vendor-submitted or audited claim, and are not blended into a single score.

CVE severity over timeUI-24 — CVE severity timelineEvery known CVE with a disclosure date and severity, plotted by when it was published — lets you see whether disclosures are trending toward more or less severe, not just a raw count. Same NVD-sourced, name-matched data as the list below.

LOWMEDIUMHIGHCRITICAL2023202420252026CVE-2026-50590 · MEDIUM 4.5 · 2026-06-05CVE-2020-36519 · MEDIUM 4.9 · 2022-03-16

Known CVEs (2)About this listSourced from the public NVD database, matched by vendor name. This is a name-based match, not exact version tracking — always check the linked NVD record for affected versions before drawing conclusions. “New” means published within the last 30 days. “Actively exploited” means CISA's Known Exploited Vulnerabilities (KEV) catalog confirms real-world exploitation, not just a theoretical severity score.
