Proofpoint Collaboration Security

Complete, Continuous Protection for the AI-Powered Threat Landscape

Extend protection across email, collaboration channels, suppliers, applications, domains, and AI-enabled workflows.

AI is transforming the threat landscape, making attacks faster to launch, easier to scale, and far more convincing. Email-based attacks saw a 94% year-over-year increase, but attacks are no longer limited to just email. Attackers are exploiting trust across multiple channels, often where employees are less guarded and security controls are less mature.

Collaboration Security helps organizations protect trusted interactions across the modern collaboration ecosystem, reduce risk, simplify operations, and confidently support AI-enabled work.

The Attack Surface Has Moved Beyond Email

Email remains a critical attack vector, but modern attacks no longer stay in the inbox. Attackers can automate reconnaissance, personalize social engineering, generate convincing impersonation infrastructure, and move across channels at machine speed.

Organizations must now protect trusted interactions across email, messaging, collaboration platforms, suppliers, cloud apps, domains, and AI-enabled workflows.

Key Callout:

The challenge is no longer simply stopping phishing emails. It is detecting earlier and securing trusted interactions wherever modern work happens.

The proof

99%

of organizations are regularly targeted with account-takeover attempts

80%

of organizations receive an attack from a compromised supplier every month.

300+

spoofed domains registered in a single day to impersonate trusted brands.

95%

of security practitioners struggle to manage multiple tools — the average organization runs 30+ of them.

Modern Attacks Are Multichannel, Multistage, and AI-Scaled

A modern collaboration attack is rarely a single event. It may begin with a phishing email, shift into messaging or collaboration tools, exploit a compromised account, abuse a trusted supplier relationship, and expand through malicious URLs, lookalike domains, or AI-generated communications. Threats continue to grow year on year — and as attacks accelerate, security teams need visibility that follows the attack across channels and response workflows that help reduce dwell time before risk spreads.

Key Callout:

When attacks move at machine speed across channels, security teams need visibility, correlation, and response that move with them.

Collaboration Security Requires a Hybrid Architecture

In the AI-powered threat landscape, no single control can solve the collaboration security challenge. Modern novel attacks exploit people, identities, suppliers, applications, domains, communication channels, and AI-enabled workflows.

A complete strategy requires four capabilities:

1

Speed and efficacy against novel, personalized threats

Detect 31% more novel threats than other email security providers, trained on 2.1T emails scanned and 20.4T URLs analyzed.

2

Blocking with confidence and explainability

The lowest false-positive rate in the industry (1:19.7M), with AI explainability for investigative context.

3

Continuous protection with hybrid architecture

Pre-delivery, post-delivery, browser, and agentic coverage in one architecture — including industry-first pre-delivery detection for prompt-injection attacks.

4

Protection wherever business communication happens

Stop cross-domain attacks across chat, apps, suppliers, and AI agents.

Key Callout:

Proofpoint Collaboration Security is the only platform built to deliver all four capabilities in a single, hybrid architecture — detecting earlier, reducing risk, and protecting trusted interactions across modern work.

ACCOUNT TAKEOVER PROTECTION

Build a Layered Defense—From Prevention to Response

> Current Foundation: Your organization already trusts Proofpoint to protect email. You have a strong foundation for defending against advanced email threats, phishing, malware, malicious URLs, and business email compromise.

> What Has Changed: In the AI-powered threat landscape, attackers can move faster from email into collaboration platforms, messaging applications, cloud environments, suppliers, and compromised identities. A threat may begin in the inbox, but it may not stay there.

> Operational Challenge: Security teams need visibility into where an attack started, where it moved, which users or accounts were exposed, and what actions are required to contain it.

> Next Best Step: Add Account Takeover Protection to close this gap — detecting compromised accounts and automating containment in minutes, not days — alongside Messaging Protection and SSO Password Guard to stop the initial compromise via blocking credential phishing and detecting corporate password exposure before they escalate.

> Outcome Message: Extend your strong email security foundation into a broader collaboration security strategy that protects users across channels, detects account compromise earlier, reduces dwell time, and accelerates response to AI-scaled multichannel attacks.

Stop initial compromise across channels attacks

Modern attacks may begin in email, but they often move into messaging apps, collaboration tools, cloud environments, or trusted business workflows. Extending protection beyond the inbox helps security teams detect movement across channels earlier and respond before risk spreads.

Protect against
account takeover

Detect compromised accounts and automate containment in minutes, not days, so attackers lose access before real damage is done e.g. fraud, data loss, etc.

Close credential and messaging gaps

SSO Password Guard detects corporate password misuse before it leads to compromise, while Messaging Protection extends detection to threats delivered outside the inbox.

Simplify investigation
and response

When attacks span multiple channels, disconnected tools can slow investigations and create visibility gaps. A more integrated approach — stopping 27–31% more threats than legacy tools — helps security teams understand where an attack started, where it moved, and what needs to be remediated faster.

SUPPLIER THREAT PROTECTION

Defend Against Compromised Supplier Accounts

> What Has Changed: Attackers increasingly hijack trusted supplier and third-party accounts to launch attacks that pass every authentication check because they come from real, legitimate accounts. These attacks move across email and collaboration channels, exploiting relationships your organization already trusts to deliver BEC, credential phishing, fraud, and malware.

> Operational Challenge: Security teams often lack visibility into supplier account compromise, making it difficult to know which trusted relationships have already been exploited, or which users and business functions are most exposed if one has.

> Next Best Step: Add Supplier Threat Protection to close this gap. Powered by Proofpoint Nexus AI, it continuously baselines normal communication patterns between your organization and its suppliers, then flags deviations - unusual volume, new recipients, shifting content that signal compromise, even when a message is fully authenticated.

> Outcome Message: Close one of the most exploited blind spots in modern collaboration security. 80% of organizations are targeted by a compromised-supplier attack monthly, and these incidents take an average of 267 days to detect, time attackers spend moving through your environment. With continuous supplier visibility and detection that doesn't depend on authentication alone, your organization can catch compromise earlier and reduce exposure to the kind of breach that costs $4.9 million on average.

Detect compromise, not just impersonation

Continuously baselines supplier communication patterns and flags subtle deviations, so compromise is caught even when a message passes every authentication check.

See your full supplier ecosystem

Get continuous visibility into every supplier interacting with your organization, including newly observed third parties, so nothing stays invisible until it's already a problem.

Protect users without disrupting business

Apply adaptive safeguards like warning tags and automatic link isolation, so employees can safely engage with legitimate-looking supplier communications without blocking normal business flow.

Accelerate investigation and response

Correlate supplier compromise with communication history and account takeover signals in one place, so analysts can prioritize response and contain multistage attacks faster.

HUMAN RESILIENCE & SECURITY AWARENESS

Build Human Resilience Beyond Awareness

> Current Foundation: Your organization already trusts Proofpoint to protect email, and recognizes that users are central to reducing risk.

> What Has Changed: In the AI-powered threat landscape, attackers personalize social engineering, impersonate trusted relationships, and automate reconnaissance faster than static, once-a-year awareness training can keep pace with. AI-generated phishing already earns a 4.5X higher click rate than traditional phishing — proof that static training alone isn’t enough.

> Operational Challenge: Awareness alone cannot protect every trusted interaction users are asked to trust. Organizations need adaptive, threat-informed education tied to real user behavior and real-world threat exposure — not a training completion checkbox.

> Next Best Step: Add Human Resilience & Security Awareness to move from static awareness training to adaptive, threat-informed coaching that changes behavior.

> Outcome Message: Move from awareness as a standalone checkbox toward measurable behavior change — reducing real-world malicious-link clicks by as much as 40% within six months of deployment.

IMPERSONATION PROTECTION

Protect your trusted business communications from being hijacked

> Current Foundation: Your organization already trusts Proofpoint for Core Email Threat Protection — and may also rely on Proofpoint or others to prevent account takeover or for end-user security awareness but that still leaves a critical gap.

> What Has Changed: Cybercriminals are using AI to increase the speed and scale of impersonation-based attacks, such as domain spoofing, lookalikes, and compromised suppliers to hijack trusted business communications. As environments become more AI-enabled and identity-driven, domains, brand, and machine-generated communications are increasingly targeted.

> Operational Challenge: These tactics exploit gaps your organization currently may not be equipped to close: domain spoofing that bypasses weak or partial authentication, lookalike domains that abuse your trusted brand, compromised suppliers and SaaS partners sending from fully authenticated accounts, and machine-generated email with little to no oversight.

> Next Best Step: Add Impersonation Protection to stop attackers from abusing your brand or hijacking your trusted business communications, with expert-guided domain authentication, malicious lookalike detection and takedown, supplier threat protection, and control over application, device, SaaS, and AI-generated email.

> Outcome Message: Complete your collaboration security journey by unifying protection across people, identities, suppliers, applications, domains, messaging channels, and AI-enabled workflows, all within a single integrated platform. When you reach maximum protection through Collaboration Security Prime, you could achieve similar benefits to what independent research found, which were a 237% ROI over three years, a 75% lower likelihood of a major breach and a 40% lower total cost of ownership.

Why This Matters Now

Attackers are already using AI to move faster than most defenses can react — automating reconnaissance, personalizing social engineering, and striking across more channels at once. Security teams are covering more ground with the same resources, and the gap keeps widening. Every day without action adds real exposure — today, the average breach costs $4.9 million.

The proof

Email-based threats grew 94% year over year, from 2.8 billion in 2024 to 5.4 billion in 2025.

AI assistants, autonomous agents, and AI-enabled workflows are moving into everyday business processes.

AI-related threats are appearing across email, SaaS/cloud apps, collaboration tools, messaging, file-sharing environments, and AI-enabled workflows.

Attackers are using AI to accelerate reconnaissance, personalize social engineering, and create more convincing impersonation infrastructure.

Account takeover, compromised suppliers, malicious URLs, lookalike domains, and impersonation continue to create operational and business risk.

Organizations report difficulty managing multiple security tools and correlating threats across disconnected channels and control points.
