At re:Invent 2025, AWS unveiled 3 frontier AI agents: Kiro Autonomous Agent, AWS Security Agent, and AWS DevOps Agent. They can operate for extended periods and are redefining software development forever.
Amazon Web Services is pushing deeper into autonomous software development, and this time it’s aiming straight at enterprise workflows. At its re:Invent 2025 showcase, AWS previewed three new AI agents, including Kiro, an autonomous agent built to operate for days without human intervention. The company calls them “Frontier Agents”, and they sit at the center of Amazon’s newest attempt to reshape how companies build and run software.
Meet Kiro: The AI Agent That Codes While You Sleep
The Kiro autonomous agent builds on Amazon Web Services' existing Kiro coding tool, which launched back in July. But this version goes further.
AWS CEO Matt Garman, during his keynote at AWS re:Invent on Tuesday, said.
“It actually learns how you like to work, and it continues to deepen its understanding of your code and your products and the standards that your team follows over time.”
According to Garman, you can pull a task from your backlog, assign it to Kiro, and walk away. The agent figures out how to complete the work on its own. It scans existing code. It learns your team's patterns. It remembers your preferences over time.
AWS is framing Kiro as a solution for teams drowning in legacy workloads. Large enterprises running old Java, .NET, or PHP systems often struggle with refactoring. Amazon believes these AI agents can cut through years of accumulated tech debt.
AWS Security Agent: The Virtual Bodyguard for Your Code
Amazon Web Services also rolled out the AWS Security Agent. Security teams often struggle to keep up with the speed of development, usually finding vulnerabilities way too late. This new agent acts as a virtual security engineer who sits with your team from day one. It reviews design docs and scans code for risks before they ever hit production.
Even great, it can perform penetration testing on demand. What used to take human testers days can now be fixed in hours. This allows developers to move fast, ensuring that security isn't just an afterthought but a core part of the build process.
DevOps on Autopilot: Fixing Crises Before You Wake Up
The third highlight of the re:Invent 2025 was the AWS DevOps Agent. This agent is your always-on firefighter. It monitors your systems, spots issues, and finds the root cause faster than a human can. Amazon says this agent has already handled thousands of internal escalations with an 86% success rate in identifying the problem. It doesn't just fix things; it gives you advice on how to stop them from breaking again.
New Chips And “AI Factories” Support The Agents
To run these AI agents at the enterprise level, AWS also introduced new chips and what it calls “private AI factories.” These are environments inside AWS designed to help companies train, store, and operate their models without putting sensitive data at risk. The chips include new versions of Trainium and Inferentia. Amazon says the improvements reduce costs for companies planning to deploy heavy AI agents like Kiro inside their existing AWS cloud setups.
Is the Autonomous Future Finally Here?
This trio represents a major shift in strategy for Amazon Web Services. They are betting big that companies want AI agents that can handle the low-ranking work autonomously. The Kiro autonomous agent and its siblings are not just about speed; they are about freeing up human developers to focus on the creative, hard stuff.
The tools you use tomorrow won't just assist you; they will work alongside you. Whether it is the Kiro autonomous agent writing code or the DevOps agent fixing servers, the autonomous future isn't coming; it is already here.
