What it sells: Data Theorem

What Mobile Secure does[2][6][8]
Mobile Secure provides automated security and privacy testing for every iOS and Android release. Mobile Secure signs in to your apps and tests every screen of every release.
What Mobile Protect does[2][3][7][13]
Mobile Protect blocks hooking frameworks, debuggers and re-signed copies inside the app. Mobile Protect scores every session and flags likely fraud to your team. Mobile Protect includes SSL pinning built on TrustKit.
What Code SAST Secure does[3][5][8][14][16]
Code SAST Secure scans your code and dependencies. Code SAST Secure secures your code, open source libraries and vendor SBOMs in one place. Code SAST Secure catches infrastructure as code misconfigurations in the repository, before they ship.
What API Secure does[2][5][8][13][15]
API Secure scores every operation on its own across authentication. API Secure probes your APIs from outside, then signs in as two different users. API Secure spots the abuse and tells the WAF you already run what to block.
What Cloud Secure does[2][5][8][16]
Cloud Secure covers the resources, roles and data behind the APIs. Cloud Secure runs the same IaC checks on what is deployed, and secures the containers and registry images your APIs and apps run on.

What it sells: Fleuret AI

What Émile does[4][6]
A separate validator confirms every finding with a non-destructive exploit. Every finding ships with a working, replayable exploit. Each finding lands as a ticket with its exploit, an owner and a remediation, pushed to Jira, Linear or Slack.
What Hortense does[4][5][6]
Hortense maps a customer's estate from domain to database. Hortense crosses what changed in the code with what is exposed on the internet and what past pentests found. Hortense prepares the scope, and a person with launch rights starts the pentest, which Émile runs. Hortense comes with every yearly plan.
