Plerion secures your cloud and the AI agents running in it, using autonomous agents of its own. They investigate every finding across AWS, Azure, GCP and Kubernetes, work out which ones an attacker can actually reach, and ship the fix as a pull request for your engineers to approve.

Your developers are shipping faster than ever, and so are the agents writing code alongside them. Every new model endpoint, MCP server and service role becomes something an attacker can try to reach. Detection tools answer that with more alerts. Plerion’s autonmous agent, Pleri, picks each finding up instead. She traces it back to the Terraform or IAM policy that caused it, finds the engineer who owns the resource, raises the fix, and follows it through to merge.

What are the key features of Plerion?

• Security agents that close findings: Pleri investigates, checks exploitability, raises the PR and Jira ticket, pings the owner in Slack, and confirms the fix once it’s merged. Every change is yours to approve.
• Security for AI agents and models: Plerion inventories every AI model, agent and MCP server across AWS, Azure and GCP, including the ones nobody told security about. It treats each agent as an identity to govern: what it can reach, and what it’s allowed to do unattended.
• Attack path analysis: Plerion Core maps every asset, identity, permission and workload into one graph and reads it the way an attacker would. Around 90% of a typical backlog turns out to be unreachable and gets retired.
• Cloud to code: A risk found in production is traced to the repo and line of infrastructure code that created it, so it gets fixed at the source.
• Built for agentic workflows: Pleri works in Slack, the browser, the CLI and over MCP, so your own agents and CI pipelines can call her directly. Plerion connects to GitHub, Jira, PagerDuty, ServiceNow and 30+ other tools.
• Compliance across cloud and AI: More than 50 frameworks, including OWASP Top 10 for Agentic Applications, OWASP LLM Top 10, NIST AI RMF, ISO 42001, SOC 2, ISO 27001, PCI DSS and NIST CSF. Regional frameworks are covered too: APRA CPG 234, the ACSC Essential Eight and MAS TRM.
• Agentless and on AWS Marketplace: Live in minutes with no software to deploy. You can buy through AWS Marketplace against your existing AWS commitment, with a free trial.

What benefits can users expect from Plerion?

• A short list of real risks: “Instead of 300 vulnerabilities, now there’s five or six actual true things we need to work on.” Michael York, SavvyMoney.
• Fewer alerts to chase: Deputy cut the alerts its team investigates by 80%.
• Capacity without hiring: “We’re seeing the equivalent of 2–3 full-time engineers’ worth of productivity gains.” Robert Mitchell, Principal Security Engineer. Basis eliminated 40 hours a week of manual review.
• Assurance you can show: Healthdirect’s stakeholders saw measurable security improvement, which carried through to lower cyber insurance premiums. WorkflowMax halved its audit preparation time.
• Knowing instead of assuming: Security leads can say which risks are closed, which are in review and which are blocked, with an owner, a PR and an audit trail behind every fix.

Plerion is a cloud-native application protection platform (CNAPP) built for software companies whose security team is outnumbered by the engineers, and now the agents, shipping code. It’s rated 4.7 on G2 and trusted by teams across Australia, the US and Southeast Asia.

How do MSPs and partners use Plerion?

Managed service providers, MSSPs and cloud consultancies run Plerion across their whole client fleet from one partner login, with each client’s data isolated to its own tenant. Pleri scores exploitability against each tenant’s actual configuration, so the same CVE gets a different answer in each customer’s environment. Engineers stop repeating the same investigation account after account. Mantel, the 2026 AWS Consulting Partner of the Year for Australia and New Zealand, cut triage and investigation time across its managed tenants by more than 60%.

For eligible customers, partners can get up to $50,000 off a Plerion subscription, funded by AWS.
