A human answers for every change
AI does the legwork and never takes the decision. Consequential fixes wait for a human supervisor, the rest run under that person’s oversight, and the record shows who decided what.
Someone still answers for what your infrastructure does.
We built NEBU so that person can keep up: exposures found and fixed under supervision, inside your trust boundary, with a record of every decision.
How NEBU started
On call
In the platforms Abdul ran, outages kept tracing back to the same cause: a misconfiguration nobody had caught in time.
A business problem
He took it to Abdou, and in July 2024 they founded NEBU through Antler. Nearly fifty interviews later, it looked less like an engineering fault and more like a business risk, reaching into security, compliance and the ability to prove what had changed.
The shift
Meanwhile, the population changing infrastructure kept growing. Service accounts, API keys and AI agents now act faster than any team can review, under controls designed for people. Finding exposures stopped being the hard part. Closing them safely, and proving it, became the work.
What we built
NEBU answers with one supervised loop. It takes each exposure from discovery to a documented fix that can be reversed, inside the customer’s own environment, and keeps the proof.
What we hold to
Ethical use of AI
AI should sharpen your team’s judgment, never hide its own. Every suggestion comes with the evidence behind it, models see only shielded data from an endpoint you control, and raw infrastructure data is never used for training.
Zero trust by design
Nothing is trusted by default, NEBU included. Each fix is planned before it runs, executes with the least privilege it needs and lands in an append-only record, inside your boundary and under your own identity and access controls.
Sustainable by design
Sustainability is designed into what we build from the start, not reported after the fact. Ask us how NEBU supports at least three of the UN Sustainable Development Goals alongside your ESG objectives.
The founding team
30+ years of combined experience, from two sides of the same problem.
One built software and scaled cloud platforms. The other moved data centers and ran large transformations. Both have seen what happens when infrastructure changes faster than anyone can account for.
Abdul Herbli
Co-founder and CTO
Leads product and engineering. A computer science engineer, certified DevOps practitioner and repeat founder, he started NEBU as his fifth tech venture. For years he was the one people woke up to bring systems back to life. A one-man purple team on attack and defense, he also solved bounties on HackerOne before AI-generated submissions spoiled the game.

Abdou Sairi
Co-founder and CEO
Leads strategy and go-to-market. A telecommunications engineer, project manager and digital transformation leader, he has led transformations and M&As across consulting and corporate roles. His first encounter with cybersecurity came back in 2009, on a honeypot team project for the University of Maryland, and he has since been in the war room when former employers came under major attacks.
