Where they overlap

  • Static application security testing is the primary category of both AISLE and Checkmarx.

Where they differ, field by field

  • Checkmarx is also filed under Dynamic application security testing, Software composition analysis and Application security posture management.
  • AISLE lists AISLE Snapshot. Checkmarx lists Checkmarx Developer Assist and Checkmarx MCP Server.
  • Checkmarx was founded in 2006.
  • Checkmarx is owned by Hellman & Friedman, since 2020.

How they differ

AISLE sells a platform that finds, fixes, and verifies vulnerabilities in source code, and it also sells AISLE Snapshot, a one-time AI-native security audit. It connects to GitHub, GitLab, Bitbucket, and Azure DevOps, and it delivers fixes as pull requests that wait for human approval. Checkmarx sells Checkmarx Developer Assist, which delivers security guidance inside a developer's IDE, and Checkmarx MCP Server, a gateway that bridges AI development assistants with the Checkmarx security platform. CISO Tribune files Checkmarx under four categories: Static application security testing, Dynamic application security testing, Software composition analysis, and Application security posture management.

The overlap is in code, dependency, secrets, and infrastructure-as-code analysis, though the working point differs. AISLE reads repositories and can run managed, in a customer's cloud account, on the customer's GPUs, or disconnected. Checkmarx scans as developers edit files, with plugins for IDEs such as VS Code, Cursor, and JetBrains and for AI coding agents such as Claude Code. Checkmarx has been owned by Hellman & Friedman since 2020 and was founded in 2006.

On November 10, 2026, AISLE announced that Cohere had formally acquired it and that customers would be served as Cohere Cyber. AISLE names the OpenSSL Foundation, which has it analyze every pull request, and the curl project, which has found and fixed 35 CVEs and 160 bugs with it. On July 28, 2026, Checkmarx announced Checkmarx Fusion, a hybrid scanning approach in early access to its customers. On April 27, 2026, Checkmarx disclosed that its investigation into a supply chain security incident found a cybercriminal group had published company-related data on the dark web.

What it sells: AISLE

What AISLE Snapshot does[2][10]
An enterprise ran a one-time AI-native security audit, AISLE Snapshot. A global network infra enterprise could not send its source code to an AI security vendor.

What it sells: Checkmarx

What Checkmarx Developer Assist does[5]
Checkmarx Developer Assist provides real-time detection, remediation and actionable insights as developers write or refine AI-generated and existing code. It comprises two main elements, Realtime Scanning and Agentic-AI Remediation. Plugins exist for IDEs and for AI coding agents.
What Checkmarx MCP Server does[5]
The Checkmarx MCP Server defines the tools and APIs that allow AI agents to interact with Checkmarx cloud services from within the IDE. The MCP Service is installed automatically once the developer authenticates in the IDE.

About AISLE

AISLE sells a platform that finds, fixes, and verifies vulnerabilities in source code. AISLE continuously finds, verifies, and fixes vulnerabilities in code, and it can run in any deployment environment with the AI of the customer's choice. Cohere has formally acquired AISLE, and customers are served as Cohere Cyber.[5]

AISLE uses thousands of agents that reason in parallel across a codebase, its dependencies, and its architecture. AISLE connects to GitHub, GitLab, Bitbucket, and Azure DevOps, then reads the branch the customer nominates, maps the stack and the build system, and identifies the dependencies. AISLE analyzes source code, dependencies and licenses, secrets, and IaC configs. AISLE reasons through code, looking at how data moves through it, what is reachable, and what an attacker could exploit. AISLE combines static reasoning with dynamic analysis via AI-guided fuzzing. AI-native analysis in AISLE covers Python, JavaScript, TypeScript, Java, C#, C, C++, Rust, Go, PHP, Kotlin, Swift, Ruby, and more.[5][6]

For dependencies, AISLE finds vulnerabilities, assesses whether the dependencies actually get used and exposed, and flags dependencies that violate license policies. AISLE analyzes credentials, keys, and tokens in repositories. AISLE reviews Terraform, CloudFormation, Kubernetes, and Dockerfile configs to find misconfigurations and propose fixes before deployment. Customers describe their trust boundaries, intent, and policies in plain English.[6]

AISLE ranks every issue by exploitability, reachability, and impact, not just CVSS. AISLE checks every finding with multiple, independent agents to verify exploitability. AISLE assesses findings based on a customer's threat model and the feedback the customer gives it. Customers can chat with the platform to inspect the evidence for each prioritization decision. A customer who disagrees with a triage decision can explain why and send the issue back through triage, and AISLE re-assesses it and applies that reasoning to future prioritization across the repository. AISLE ingests and prioritizes issues from third-party scanners in the same workflow as AISLE findings. Customers tell the platform what to do with low, medium, high, and critical severity findings.[7]

AISLE builds the repository in an isolated container, applies the patch, and runs the tests against it. AISLE uses both CI and agent-generated sandboxed tests to verify each fix it generates. AISLE does not merge fixes on its own, and it opens the pull request and waits for human approval. AISLE fixes code and dependency findings, and it provides remediation guidance for secrets, license policy, and infrastructure-as-code findings. AISLE bumps a dependency to the fixed version and edits code to adapt to any API changes. AISLE explains each change in natural language and delivers its fixes as pull requests. AISLE resolves findings with a round of confirmation analysis that runs automatically after a fix is merged. Customers decide how far AISLE goes on its own, per severity and per repository.[8]

AISLE does not train on customer code. AISLE builds context at the repository, product, or codebase level, updates it with every run, and reads it before analyzing new findings. Customers can dismiss a finding and explain why in natural language, and AISLE turns the reasons into guidance. Everything AISLE learns about a repository is visible, editable, and dated. Customers can accept a risk for a given amount of time, and AISLE resurfaces it when the time is up.[9]

AISLE can run the infrastructure while the customer connects its repositories, for teams whose code classification allows external processing by frontier LLMs. AISLE can run inside a customer's cloud account using the customer's choice of frontier and custom LLMs, with deployment artifacts delivered in push or pull mode into a local registry. AISLE can run on the customer's GPUs, using custom models recommended by AISLE, plus optional threat and dependency intel pulled from AISLE servers. AISLE can run disconnected using fine-tuned security models, with no network path in or out. AISLE provides single-tenant cloud deployments in the region of the customer's choice. AISLE maintains a zero data-retention policy with every model provider, and none of a customer's data is used for training. AISLE is not bound to a single model vendor or a fixed list of languages.[5][6]

The OpenSSL Foundation has AISLE analyze every pull request. The curl project, maintained by a full-time team of one, has found and fixed 35 CVEs and 160 bugs with AISLE. An enterprise ran a one-time AI-native security audit, AISLE Snapshot. A global network infra enterprise could not send its source code to an AI security vendor.[1][3][5][9][10]
