OVERVIEW

Stop emerging and AI-powered attacks with continuous protection

A modern collaboration security solution protects people and business communications from threats across email, messaging, and cloud apps. As AI enables faster, more personalized, more evasive attacks, an effective solution must apply the right protections at the right moment: before delivery, after delivery, at click time, and at login time to stop novel threats at the inbox and beyond.

Reduce risk across major threat vectors

Block sophisticated attacks while reducing repeat attack risk through targeted, threat-informed learning.

Accelerate security operations

Correlate security events across channels, automate response, and connect threat protection with user-risk workflows. 

Consolidate security tools and teams

Replace fragmented point solutions with an integrated platform that improves operational efficiency and lowers costs.

WHY IT MATTERS

AI has doubled the attacks targeting your people, everywhere they work

Attackers abusing AI can now generate novel threats at machine speed, constantly changing the indicators traditional tools rely on. Global email threats grew 94%—from 2.8 billion to 5.4 billion—in just one year. The threat extends beyond email: nearly half of AI-related attacks now move into collaboration channels such as cloud apps and supply chains, where they can escalate into credential theft, account takeovers, conversation hijacking, and follow-up attacks. 

As threats adapt and move across environments, point-in-time detection can no longer keep up. Organizations need continuous security built to protect collaboration as attacks evolve.

Frequently Asked Questions

Point solutions secure one channel at a time — a secure email gateway for email, a separate DLP tool for file sharing, a separate platform for security awareness training. Each tool works in isolation, so a threat signal detected in one channel doesn't carry over to protect the others. A collaboration security platform correlates activity across email, messaging, cloud apps, and the supply chain from a single detection and response layer, so a threat flagged in one channel automatically informs protection everywhere else — closing the blind spots that come from managing disconnected tools.

A secure collaboration platform should protect more than one communication channel. Look for continuous threat detection, protection against phishing and account takeover, security for third-party communications, automated response, and controls that address human risk. Enterprise tools should also work across the email, messaging, and cloud collaboration services your teams already use.

Secure collaboration tools combine threat detection with controls that act before and after users interact with an attack. They can block phishing, inspect malicious URLs in real time, detect compromised accounts, and automate remediation. Connecting activity across email and collaboration tools also helps security teams identify and contain multistage attacks faster.

Organizations can strengthen Microsoft Teams security by protecting users against malicious links, phishing, account compromise, and other threats that native controls may not address alone. Real-time URL inspection and cross-channel threat intelligence can help protect team communication in Microsoft Teams, Slack, chats, and other collaboration tools.

Secure collaboration helps detect compromised supplier and third-party accounts before attackers can exploit trusted business relationships. By connecting threat intelligence across email, cloud apps, accounts, and other communication channels, organizations can identify suspicious activity sooner and reduce the risk of phishing, account takeover, and follow-up attacks.

A collaboration security platform supports human risk management by evaluating each person's actual risk profile — their role, behavior, and exposure to real attacks — rather than applying generic training to everyone equally. Real attacks identified in email, Teams, or other channels convert directly into targeted simulations and just-in-time coaching, so employees learn from the specific threats they're actually facing. Behavior-change analytics then show whether risk is actually going down, not just whether training was completed
