The Shift from Email to Collaboration Attacks: What You Need to Know

Why Collaboration Apps Have Become Today’s Biggest Security Gap

Email may still be the number one entry point for cyberattacks, but it’s no longer the only one. As organizations increasingly rely on Microsoft Teams, OneDrive, SharePoint, Google Drive, Slack, and other collaboration platforms, attackers have followed this trend too. These tools make communication faster—but they also create new, often unprotected pathways for malware, phishing links, and data theft.

The challenge is that most security stacks still focus on email alone. Native cloud security tools inspect inbound messages, but they rarely extend the same level of protection to files shared in chat, links dropped into channels, or documents synced across cloud drives. Once an attacker compromises a single account, they can move laterally through these collaboration tools without triggering traditional email defenses.

Modern protection closes this gap by scanning files, links, and shared content across all major collaboration platforms in real time. Threats are blocked before users interact with them, and malicious documents are sanitized automatically, ensuring safe productivity without disruption. This approach delivers unified visibility and defense across the entire communication ecosystem—not just the inbox.
