Unifying Collaboration Security with Behavioral AI

AI Changed the Attack. The Inbox Isn't the Only Target Anymore.

Attackers aren't just sending more phishing; they are using generative AI to personalize social engineering at scale and bypass your traditional security filters and siloed AI platforms. This exploit allows them to target your unprotected human layer across both email and collaboration channels.

Generative AI has industrialized the threat landscape

Attackers have automated social engineering into dynamic, conversational exploits. With campaign message volumes surging by 450%, manual SOC queue review is no longer viable. Understaffed teams are drowning in noise while critical threats wait to be acknowledged.

Technology is fallible and missing new attacks

Static rules and signatures were built for known malware, not AI intent. Traditional perimeters suffer a 30% to 63% miss rate on BEC and up to 76% on link attacks. When tech fails, silent black-box systems leave users completely unequipped.

Attackers move laterally into Microsoft Teams

Attackers know users inherently trust internal chat. Today, 1 in 5 attacks on Microsoft Teams are multi-channel, using email to establish contact and chat to execute the exploit. Securing the inbox alone leaves a massive backdoor wide open.

135 armed & dangerous attacks reaching the average 1,000-user org every year.

Explainable Multi-Engine AI Detection

Five specialized engines analyze message copy, sender relationships, email headers, links, and attachments simultaneously. Instead of a black-box risk score, admins see the exact technical reasons behind every verdict.

Point-of-Risk Teachable Moments

Contextual coaching, real-time nudges and localized banners and tags (in 13 languages) show users why a message is suspicious the moment it occurs, stopping 97% of users from clicking, replying, or proceeding with a high-risk send.

Data Loss Prevention & Misdirected Send Protection

Outbound semantic NLP and social graph baselines analyze conversational context, user history, and recipient relationships. Prevent flags PII, PCI, lookalike domains, and autocomplete mistakes before an email leaves the building.

Threat Intelligence

KnowBe4 Threat Labs converts real-world attack telemetry and 15+ years of data into live detection models across our Collaboration Security suite, continuously updating defenses before new patterns hit your users.

Behavioral AI Built to Understand Your Workforce

Unlike black-box API tools that operate silently behind closed doors, KnowBe4’s behavioral AI combines automated threat containment with complete administrative visibility. We show your analysts the explicit linguistic and relational signals behind every verdict while turning every technical catch into coaching that actively improves workforce behavior.

Don't Just Take Our Word For It

"What I like most is AI and machine learning and real-time user feedback and coaching. Not only does it tell you if the email is phishing or spam, but it also tells why it is. Knowing the why will increase education and knowledge with spotting phishing and threats."

Director IT Security and Risk Management — Banking Industry (Gartner Peer Insights) Read review

"We have been a long time KnowBe4 customer using the phish training. By adding their email security tool, we were able to simplify our infrastructure, improve our phish-prone rating and strengthen controls on outbound emails."
