About Plerion

Plerion calls Pleri its primary AI security agent.[2]

Plerion addresses a backlog that no security team works through manually once ten developers use AI coding assistants. Plerion describes a finding that spans a service, a team, and a vendor, and that nobody picks up because nobody is sure whose job it is. Plerion states that 46% of code shipped today is AI-generated, while the list of issues that took a week to triage is still taking a week.[2]

Plerion shows what agents can access and what they can do. Plerion traces each agent to the code, identities, infrastructure, and data it touches, so that teams can fix the risks that matter.[2]

Plerion's agent investigates findings, decides whether they need dealing with, and submits a fix. The engineer who owns the resource reviews and approves the change.[2][3]

Pleri orchestrates a set of specialist skills, each covering a different part of the cloud estate.[2]

Plerion publishes an article based on the AIS-05 control from the CSA Cloud Controls Matrix v4.0.10, dated 2023-09-26. Plerion's article on automated application security testing covers considerations, strategies, and practices for implementing that testing based on guidance in the Cloud Controls Matrix of the Cloud Security Alliance.[2][4][6]

Plerion's data security guidance notes that the DSP-01 control maps to several other industry standards and regulations related to data privacy and security.[1][2][3][4][5][7][8][9][10][11][12][13][14]
