Néréus The intelligence that connects everything

Not all risky emails are immediately identifiable. Some fall into a gray area: credible enough to slip under the radar, yet suspicious enough to represent a risk.

Predictive Ban continuously analyzes these emails and identifies the ones your employees would likely have rejected. It blocks them upstream, before they even reach the inbox.

Fewer suspicious emails to sort through. Fewer decisions to make. Less exposure to risk.

Reduces risk exposure without adding friction for your teams.

Continuously monitors malicious email campaigns by cross-referencing multiple threat intelligence sources, detection of sites impersonating known brands, and signals of urgency or authority used by attackers. Result: +35% spear-phishing detection and +13% spam detection over the first five months of the year.

Stays one step ahead of the most targeted and sophisticated attacks.

Wave Block detects malicious email campaigns from their very first waves and blocks them before they gain momentum. Its model distinguishes attack waves from legitimate mass mailings, allowing it to act quickly without disrupting expected communications.

Cuts short large-scale attack waves before they spread.

Multi-Signal Detector complements previous protections with an individual analysis of each message, in order to intercept what escapes mass detection, i.e. around 6% of total flow processed.

Each email is individually assessed for its probability of being spam, based on binary features describing the sender, subject, and body of the message, as well as its presence in this note’s dynamic list (H52). This is not a deep semantic analysis, but a targeted evaluation that reinforces overall detection.

Lets nothing through, including targeted and discreet attacks, too rare to be caught by mass detection.

Secure Link is Mailinblack’s proprietary anti-phishing technology that analyzes links at the very moment they are clicked.

Each link in an incoming email is rewritten and encrypted, then submitted to a triple AI analysis: the morphology of the link, its semantics (words or impersonated brands), and the content of the destination page. The origin of the email is also verified based on Secure Link’s data. In case of danger, the user is instantly warned.

Protects against hidden threats within malicious links.

Swift Threat Response draws on Mailinblack’s collective intelligence: a threat detected at one client automatically becomes a protection for the entire fleet. The same behavior blocked at several clients within 48 hours is neutralized everywhere, with a threshold calibrated to keep false positives under 1%.

Result: significantly more precise detection than random blocking, and several billion emails neutralized every year thanks to this collective protection.

Turns every individual attack into instant collective protection.

Precision Filter is an intelligent analysis engine dedicated to email filtering, cross-referencing multiple signals to identify at-risk messages. It relies on LabEngine, a rule-injection module that generates new detection rules in real time, without waiting for a full update cycle, in order to react quickly to emerging threats.

These protections are complemented by Data Leak Prevention technology, which prevents client-side leaks of sensitive data, such as passwords or banking credentials.

Detects, adapts in real time, and protects sensitive data at every stage of filtering.
