Co-founder · Business Development
Supports companies in growing their business, strategy, revenue, and development.
Umbra Penance was founded by Adel Acheli, a software and cybersecurity engineer who has shipped multi-tenant SaaS, internal tools, AI features, hundreds of production automations, and delivered penetration test reports for live systems, each one designed with tenant isolation, least-privilege access, and pre-release security review built into the architecture, not bolted on after.
Every engagement has a single point of accountability from architecture to deployment. Code is reviewed the way an attacker would read it, and every project closes with documentation you can act on.
