AWS re:Invent 2025: A new era for AI, security, and partner innovation

AWS re:Invent 2025 wrapped, leaving thousands of cloud and security leaders from around the world with a clear vision for the future. The energy in Las Vegas reflected the industry's rapid momentum and the growing importance of collaboration in solving complex challenges. For Mimecast, attending the event was an opportunity to connect directly with customers and partners, gathering valuable insights into their priorities and the evolving threat landscape.

This year's conference was defined by three interlocking themes that are shaping the landscape for innovation, differentiation, and growth: the rise of agentic AI, a deep focus on security and responsible innovation, and a significant expansion of the partner ecosystem. These developments are highly relevant for ISVs in the AWS security ecosystem, and they reinforce our commitment to customer-centric innovation and building resilient solutions in collaboration with AWS.

Celebrating the power of the ecosystem

A major focus at re:Invent 2025 was the power of the partner ecosystem. Keynotes and sessions consistently highlighted how multi-partner solutions are essential for addressing today's complex security and compliance challenges, especially in multi-cloud environments. There is a clear demand for integrated, outcome-driven solutions that combine the best technologies from multiple vendors.

To meet this demand, AWS announced Multi-Product Solutions in the AWS Marketplace. This feature allows customers to purchase integrated offerings from multiple vendors through a single, streamlined contract, simplifying procurement and accelerating time-to-value. Mimecast is committed to collaborating with AWS and our partners to deliver these kinds of integrated solutions.

The event also continued its tradition of recognizing partner excellence. We extend our congratulations to our peers who received major awards for their achievements. CrowdStrike was named AWS Global Security Partner of the Year and Global Marketplace Partner of the Year, becoming the first ISV to surpass $1 billion in AWS Marketplace sales in a single year. Zscaler was recognized as AWS Marketplace Partner of the Year for North America, and SentinelOne was honored as a Security Partner of the Year finalist. These recognitions validate the power of collaborative innovation and underscore the importance of building solutions that span multiple security domains.

From generative to agentic: The evolution of AI

One of the most significant shifts at re:Invent 2025 was the evolution in AI focus. The conversation has moved beyond generative AI, which primarily creates content, to agentic AI. Agentic AI refers to autonomous agents that can reason, plan, and execute complex, multi-step tasks to achieve a specific goal. This marks a pivotal shift toward a new era of autonomous, production-ready systems that can augment human capabilities.

AWS is positioning agentic AI as a foundational layer of the cloud, not just an add-on feature. Key announcements like the introduction of Frontier Agents demonstrated this commitment. These are specialized, core AWS offerings like Kiro for software development, the AWS DevOps Agent for incident response, and the AWS Security Agent for proactive security.

To support this new paradigm, Amazon introduced Bedrock AgentCore, a new platform for building, evaluating, and governing production-ready AI agents at scale. This enables organizations to develop custom agents tailored to their business needs, with built-in safety and governance. Enhancements to the AgentCore Platform and Amazon Bedrock provide robust governance, policy enforcement, and continuous evaluation for these systems, ensuring AI deployments are safe, auditable, and compliant. For Mimecast, agentic AI presents exciting opportunities to enhance email security automation, improve threat detection, and enrich the user experience.

Building trust with security, compliance, and responsible innovation

With the rise of powerful AI systems, trust, safety, and governance were major themes. AWS announced new tools within Bedrock AgentCore for policy management, action approval, and observability. Organizations can now set granular policies on what AI agents are permitted to do, monitor their actions in real-time, and ensure every step aligns with internal policies and industry regulations. This is essential for deploying AI in security, where responsible and transparent adoption builds customer trust.

Beyond AI, security and compliance were front and center across the conference. AWS reinforced its commitment to a security-first, compliance-driven cloud with several major developments. The new AWS Security Agent, now in public preview, delivers proactive, AI-powered security recommendations from the design phase all the way through deployment. This service helps embed security earlier in the development lifecycle.

Amazon GuardDuty now offers extended threat detection for EC2 and ECS containers, helping organizations better protect workloads across their environments. Additionally, Security Hub is now generally available with near real-time analytics and improved integration capabilities. These innovations empower ISVs to build trust, accelerate compliance, and deliver secure, resilient solutions, a critical advantage for customers in highly regulated and security-sensitive sectors.

To further simplify regulatory alignment, AWS announced new certifications and assessments, including IRAP for Australia and alignment with the EU’s Digital Operational Resilience Act (DORA). This, combined with an expanding global infrastructure, strengthens the platform for ISVs serving enterprise and regulated markets.

A new go-to-market with marketplace and partner innovations

AWS doubled down on its commitment to the partner ecosystem, introducing changes that lower barriers for ISVs and foster deeper collaboration. AWS Partner Central is now integrated directly into the AWS Console, which streamlines partner management, opportunity tracking, and co-selling activities.

The AWS Marketplace also received a significant, AI-powered overhaul. New features are designed to help customers discover solutions more easily and enable ISVs to offer integrated, multi-vendor solutions. These enhancements include:

• Agent mode: A conversational AI interface that helps customers find solutions using natural language queries.
• Agentic search: AI-powered recommendations that match customer needs with the best-fit products across multiple categories.
• Multi-solution private offers: Customers can now bundle products and services from Mimecast and our ecosystem partners into a single contract, simplifying procurement.
• Express private offers: Faster deal cycles and more flexible pricing options make it easier for customers to adopt new solutions.

As a partner available in the AWS Marketplace with the “Deployed on AWS” badge, Mimecast is excited by these innovations. They reduce friction for our global customers, enhance discoverability for ISVs like us, and enable more flexible and integrated go-to-market strategies.

Looking ahead: Strategic implications for security

AWS re:Invent 2025 outlined a clear path forward for the cloud industry. For ISVs in the AWS security ecosystem, the message is that agentic AI is becoming a core differentiator, security and compliance must be deeply integrated into the cloud and AI stack, and partner ecosystem tools are unlocking powerful new go-to-market opportunities.

Aligning with these strategic themes will be critical for leading in the next era of cloud security. At Mimecast, we remain committed to delivering advanced, integrated security solutions in collaboration with AWS and our partners. The announcements from re:Invent 2025 will help us continue to innovate, ensuring our customers can confidently embrace the future of cloud and AI.
