👉 For Enterprises:
Proofpoint is no longer just about email. With its new AI-driven controls, it’s positioning itself as the “collaboration firewall” — the control point for how people and AI agents interact.
👉 For MSPs:
The pending Hornetsecurity acquisition will take MSPs from Proofpoint’s 7th-largest division to its 2nd-biggest. If you sell or manage security services, this could reshape your Proofpoint playbook.
🤔 Why you should care:
Proofpoint is redefining itself right before an IPO. The bets they’re making now will directly shape the tools you use tomorrow.
The Enterprise Strategy: Building the Collaboration Firewall
Email is still the number one threat vector. But the rise of collaboration platforms like Teams, Slack, and Zoom means attackers no longer stop at the inbox — and Proofpoint knows it.
That’s where Threat Protection Workbench comes in. Already adopted by 60% of customers, Workbench gives SOC teams a single pane of glass for threat intelligence, analysis, and remediation. It allows security teams to visualise every data-sharing event across collaboration tools and respond in real time.
Workbench is the foundation for Proofpoint’s ambition to become the collaboration firewall: a unified layer that governs how humans, data, and AI agents interact across enterprise environments.
The MSP Play: Hornetsecurity
Proofpoint’s ambitions extend beyond large enterprises.
For Proofpoint, MSPs have long been a smaller part of the business, the seventh-largest division. But assuming Proofpoint’s deal to acquire Hornetsecurity closes, MSPs will leap to the second-largest business unit.
Hornetsecurity brings a strong global MSP footprint, complementing Proofpoint’s primarily US-centric base. Together, the two companies can combine the best of Proofpoint’s enterprise-grade platform with Hornet’s partner-driven model.
For MSPs, this creates a new opportunity: a more integrated suite of tools for securing smaller and mid-sized organisations without sacrificing scale or visibility.
The deal is expected to reshape Proofpoint’s channel strategy — and partners should expect more announcements once approval comes through.
The Five Pillars of Proofpoint’s Platform
From the stage in Nashville, Proofpoint outlined what it sees as the foundational pillars of modern cybersecurity:
- Securing Email — still the most common attack vector.
- Protecting Data — through DSPM, DLP, and data lineage.
- Managing Insider Risk — covering careless, compromised, and malicious insiders.
- Securing Collaboration — extending protection across SaaS platforms.
- Defending the Agentic Workspace — safeguarding both people and AI agents.
Together, these pillars frame Proofpoint’s long-term goal: to own the control layer for human and AI interactions.
The Catch
Not everything announced in Nashville will be available soon. Tools like Satori Agents and the Secure Agent Gateway won’t roll out until 2026.
That raises a fair question: are these announcements more about IPO storytelling than immediate customer impact?
Execution, as always, is what matters. If Proofpoint can deliver these tools with the same reliability that built its email security reputation, it could redefine its category. If not, the risk is overpromising ahead of the IPO.
The Competitive Landscape
If Proofpoint succeeds, it won’t be alone. The company’s vision of securing human + AI interactions puts it in direct competition with:
- Microsoft, with Purview for data security and Entra for identity.
- CrowdStrike, expanding into identity and AI-driven detection with Charlotte AI.
- Palo Alto Networks, integrating identity into its Cortex platform.
The next two years could be defined by which of these platforms wins the battle to secure the agentic workspace. Proofpoint clearly wants to be in that fight.
Our Take
Under Sumit Dhawan, Proofpoint has shifted into high gear.
From Workbench adoption and MSP expansion to threat research leadership, the company is laying a strong foundation.
Proofpoint has the vision — now it needs to prove it can deliver.
