For years, email has been the front line of cybersecurity, receiving the lion’s share of defense tools and training. But a new survey suggests that focus may be leaving a critical blind spot wide open. The data reveals a worrying gap, with 50% of organizations admitting they lack strong confidence in detecting threats across messaging and social platforms. This isn’t just a hypothetical risk—60% of cybersecurity professionals report that attacks are already moving beyond email, targeting the very channels where your team communicates and shares files. In fact, more than half of respondents identified non-email channels as the most vulnerable to cyber-attacks, signaling a pressing need to rethink collaboration platform security.
Why Attackers Are Moving Beyond Email to Collaboration Platforms
Phishing emails still hold the top spot as the single biggest threat to organizations, with 61% naming it as their primary concern. But here’s the catch: email defenses have gotten much better over the years. Spam filters, advanced threat protection, and user training have made it harder for attackers to succeed through email alone. So, where are they going next? Straight into the channels where your guard is lower.
This shift is already happening. In fact, 60% of respondents stated that cyber-attacks are already moving beyond email. Attackers are taking advantage of what’s called attack surface expansion—the growing number of digital tools your team uses daily. Slack, Microsoft Teams, and even SMS have become prime targets because security teams often treat them as secondary concerns. The result? Threat detection confidence plummets when you move away from email.
Consider the numbers: organizations feel most confident defending email, with 83% reporting high confidence. But that confidence drops sharply for Slack (40%) and Teams (61%). That gap is exactly what attackers are exploiting. They know that collaboration platforms are full of shared links, file transfers, and quick messages—all of which are harder to scan for malicious content. These beyond email threats are not theoretical; they are already causing real damage.
To make matters worse, more than half of all respondents selected non-email channels as the most vulnerable to cyber-attacks. That means your team likely feels exposed in the very tools they use most for collaboration. The collaboration platform vulnerabilities are real, and the attackers are taking full advantage of the blind spots you haven’t addressed yet.
Comparing Confidence Across Channels: Why Slack Lags Behind Teams
That feeling of exposure isn’t uniform across all your communication tools. A detailed look at channel-specific confidence reveals surprising disparities. While organizations overwhelmingly trust their ability to stop email attacks (83%), that confidence drops sharply when you shift to other platforms. The numbers show a clear hierarchy, and the gap between the top two collaboration tools is particularly striking. Your threat detection confidence for Microsoft Teams sits at 61%, but for Slack, it plummets to just 40%. That 21-point difference is a major red flag.
Why Slack Confidence Is Lower Than Teams
Social media (51%) and SMS or WhatsApp (50%) fall in between these two extremes, but the Slack-versus-Teams divide is the most telling. The design and integration differences between the two platforms likely influence your perceived risk. Microsoft Teams benefits from deeper integration within the broader Microsoft 365 security ecosystem. If your organization already uses Microsoft’s email security tools, extending that protection to Teams feels natural and seamless. Slack, on the other hand, often operates as a standalone app. This can create a weaker Slack security perception, where you view it as a separate, less fortified channel rather than an extension of your existing defenses.
Your Microsoft Teams threat defense may also feel stronger simply because the platform is more tightly coupled with your IT admin controls. Teams policies for data loss prevention and conditional access often mirror your email rules. Slack requires separate configuration, and many teams skip that step. The result is a noticeable gap in channel-specific cybersecurity confidence. If you rely heavily on Slack for daily work, this lower confidence level should push you to review your security settings there, just as you would for email. The tools you trust for quick chats may be the very ones where threats slip through unnoticed.
The Training Gap: Infrequent and Inconsistent Education on Collaboration Threats
Most organizations do provide some form of security awareness training that extends beyond traditional email. However, the numbers reveal a worrying gap: only a minority of companies make this training a regular habit. According to recent data, just 41% of organizations train their users on a consistent, recurring basis about the specific threats found in collaboration tools like Microsoft Teams, Slack, and standard SMS messages. That leaves the majority of employees learning about these risks only sporadically, if at all.
Even more concerning is the finding that 13% of respondents stated their organizations never provide training for these channels. This complete absence of employee awareness programs for chat-based and messaging platforms directly contributes to the low threat detection confidence seen across these tools. If you never learn how a phishing link or a malicious file might arrive via a direct message, how can you be expected to spot it in your daily workflow?
The inconsistency of cybersecurity training frequency creates a real problem. When training is infrequent, the lessons don’t stick. New attack methods evolve quickly, and a one-time session during onboarding is rarely enough to keep you prepared. To build genuine confidence in spotting threats on Slack or Teams, your organization needs to shift toward regular, updated education that covers these specific platforms. Without that consistent effort, the gap in awareness will only widen, leaving your collaboration channels as the most vulnerable part of your digital workspace.
Emerging Threats on Slack and Teams: AI-Driven Attacks and Specific Vulnerabilities
Attackers are now using AI to craft phishing messages that look just like a legitimate request from a coworker. These AI-generated texts can mimic your team’s tone, reference ongoing projects, and even include realistic urgency. Because collaboration platforms rely on speed and trust, a convincing message can trick someone into clicking a malicious link or sharing credentials before they stop to think. This is why threat detection confidence is so low — the attacks feel real.
How AI Makes Threats on Slack and Teams More Convincing
AI phishing on collaboration platforms goes beyond simple typos and generic greetings. Attackers can scrape public data or leaked credentials to personalize messages. They might pose as your IT department asking you to verify your login via a shared link, or send a direct message with a document that contains malware. These Slack malware attacks and Teams social engineering attempts are harder to spot because they blend into the normal flow of work. The design of these tools — open APIs, rapid file sharing, and limited email-style defenses — creates an inherent vulnerability collaboration apps don’t have in traditional email.

Specific threats you should watch for include credential harvesting through shared links that lead to fake login pages, malicious documents sent in DMs, and impersonation of trusted colleagues or vendors. The speed of these platforms means a single click can compromise your entire workspace. In fact, non-email channels were selected by more than half of respondents as the most vulnerable to cyber-attacks. And 60% stated that cyber-attacks are already moving beyond email. That shift makes it essential to understand these emerging risks and adjust your defenses accordingly.
Tools and Controls to Boost Threat Detection Confidence on Non-Email Channels
The numbers are clear: half of organizations say they lack strong confidence in detecting threats across messaging and social platforms. And while most provide some form of training beyond email, only 41% do so regularly. That leaves a significant gap—but you can close it with the right tools and controls. Dedicated Slack monitoring tools and Microsoft Teams security controls are designed to catch what standard email filters miss. These solutions scan for suspicious links, malicious file attachments, and unusual user behaviors directly inside your collaboration channels.
For true visibility, you want these tools to integrate with your existing SIEM and SOAR systems. That way, alerts from Slack, Teams, and SMS flow into the same dashboard you already use for email threats. No more blind spots or siloed data. You can also layer in proactive policies: restrict direct messages from external contacts, enforce file-sharing rules, and enable real-time scanning for all uploaded content. These actions reduce the attack surface before a threat even appears.
Which Industries or Organization Sizes Are Most Affected by Low Confidence?
While low confidence affects many organizations, the impact varies. Industries that handle sensitive data—like finance, healthcare, and legal services—often feel the pinch more acutely because a single slip in a Teams chat or SMS conversation can lead to compliance violations. Smaller organizations with lean IT teams may struggle more, as they lack the budget or personnel to deploy dedicated collaboration platform defense solutions. However, regardless of your size or sector, the core need is the same: you need threat detection confidence that extends beyond email. By investing in specialized monitoring and clear security controls, you can turn those messaging channels from liabilities into assets.
Frequently Asked Questions
How can you improve threat detection confidence for Slack and Teams?
Start by auditing your current monitoring coverage for these platforms. Many security tools designed for email lack visibility into chat channels, file sharing, and automated integrations. Deploy dedicated detection rules that scan for phishing links, unusual login patterns, and data exfiltration attempts in real time.
Why does threat detection confidence remain higher for email than for collaboration platforms?
Email security has decades of established defenses, such as spam filters, DMARC, and sandboxing. Collaboration tools are newer, and traditional security stacks often miss their unique attack surfaces. This gap directly affects your threat detection confidence when protecting Slack and Teams compared to your inbox.
Are collaboration platforms inherently more vulnerable due to their design?
Their real-time, open-sharing design does introduce risks like easy invitation forwarding, external guest access, and persistent chat histories. However, you can mitigate these with proper configuration, least-privilege policies, and regular security awareness training for users.
