Vendor news

Funding rounds, leadership changes, incidents, new capabilities and announcements across the vendors in this catalog — collected automatically from vendors' own public feeds. Product release versions are on their own page, so the landing feed here never reads as one vendor's changelog.Where this comes fromEvery item links to the vendor's own published source: a GitHub release feed, a changelog, a status page, an SEC filing or a company blog. Nothing here is written or editorially reviewed by 0-Doubt, and nothing is a recommendation — it is machine-collected public record, labelled the same way as all other baseline content on the platform. Coverage is uneven by design: a vendor that publishes no public feed will not appear, and that absence is not a judgement about the vendor.

568 matching stories — announcement, in Email Security — showing up to 3 per vendorPer-vendor capWhile browsing, no single vendor may fill more than three slots on any one page, so a vendor with a chatty release cadence cannot buy the page you are looking at. That means a page can render fewer stories than the count above. Searching a headline or naming a vendor turns the cap off, because then you have asked to see everything that matches.

Email Security for Regulated Industries - Proof of Control | Halon

For most organizations, email security is judged by one question: did it stop the attack? For regulated organizations, that's only half the test. Banks, healthcare providers, insurers, and government agencies also have to answer a second question: can you prove why the system made that decision? Every blocked message and every policy change needs a defensible trail behind it. During an incident, that requirement becomes more important, not less. This is where email security infrastructure built

Is MFA Enough to Protect Microsoft 365 Email?

Tycoon 2FA showed how phishing can capture an authenticated session after a user completes MFA. For SMEs using Microsoft 365, stronger email security starts before the sign-in page and continues after account access. The March 2026 disruption of Tycoon 2FA exposed an important limit of common MFA methods. Attackers could relay a legitimate Microsoft 365 sign-in and capture the session created after the user authenticated. The resulting access could support payment fraud, data theft or further ph
