# Hal, Cybersecurity

> HAL is a 24/7 sentinel that attacks and defends your systems. It runs the attack a real intruder would, around the clock, keeps every finding tied to its recorded, replayable evidence, and hands back the exact fix.

### The scope

HAL watches the systems a business depends on, day and night: applications and APIs, identity and access, cloud permissions, agents and assistants, data access and business logic. It stays inside the agreed targets and permissions.

## Follow an attack from the first request to the server response.

### Guest session

The application issued a session for the guest account.

### Access denied

The protected endpoint rejected the guest session with 403.

### Token forged

The assessment recovered a weak signing key and changed the token role from user to admin.

### Admin access

The same request returned 200, and the server recorded an admin_flag event for the guest account.

## The finding stays connected to its evidence.

### The record

Every transition keeps its record: the request, the server's response and what HAL observed, read together. The original server record stays available, and every record is fingerprinted so it cannot be quietly changed.

### The remediation

Replace the weak signing key. Invalidate the affected tokens. Enforce permissions on the server. Test guest and administrator access again.

### The defense

When HAL gets in, the work does not stop at the report. It hands the team the fix, tests it again and keeps watching the door it just closed.

### AI systems

HAL also tests how agents and assistants handle adversarial content, retrieved documents and access to tools.

## Security findings

### Global software group

We uncovered a route to customer information and took it to the group's security leadership. Our evidence went into a technical review.

### Gym operator

We brought an exposed service to their IT team. They confirmed the issue was fixed and thanked us for the intervention.

### European fitness group

We traced a data exposure to an internal application. The team confirmed the affected system and asked to explore recurring audits.

### Healthcare group

We documented risks across inherited and third-party systems, with evidence, priorities and recommended corrections. The security team reviewed the findings with us, one by one.

## Graded so the attacker cannot cheat.

### The harness

Every test runs against a fresh target with its own secrets and a tamper-proof log. The scorecard sits where the agent cannot touch it, and a fake success or a do-nothing pass is a trap it has to fail.

### The engagement

Start with the targets, permissions and questions that matter to the business. HAL goes on watch and returns the path, the evidence and the change to make.

## Outcome

A sentinel the size of a red team, running the attack that matters again and again. It finds the open door before anyone else does and hands you the exact fix with the proof behind it.
