Inside the client portal

Flag it. Fix it. Prove it.

Everything lands in one portal: a live security score, a prioritised to-do list, and automation that never acts without your approval.

01 · Flag

Every risk, one register

Vulnerability scans, attack-surface monitoring, Dark Web Watch, and posture findings, scored by severity and real-world exploitability.

02 · Prioritise

A to-do list, not a data dump

Top actions ranked by risk and cost, with decisions, approvals, and recommendations in a single inbox.

03 · Fix

Remediation with guardrails

Autopilot playbooks and guided actions close the gaps. Nothing is changed without your approval.

04 · Prove

Evidence on demand

Board packs, per-framework compliance evidence, and a full audit log, ready for auditors and insurers.

Connect. Baseline. Operate.

Baseline

The platform maps your estate and builds your risk picture: a security score, a risk register, and your external attack surface.

03

Operate

Approve prioritised fixes, watch your score climb, and pull board packs when you need them. Advisers and vCISO support on tap.

What the platform solves

Findings buried in spreadsheets One ranked risk register
No idea what to fix first Top actions, by risk and cost
Fixes that stall for months Driven to done, with your approval
Audit-time evidence scrambles Evidence filed as you go
Vendor risk in email threads Live TPRM assessments

Why Penthropic

Finding risk is easy.
Fixing it is the job.

Most tools stop at the finding: a scan, a score, a PDF of problems. Penthropic is built around the fix. Each flagged risk lands in one register, gets ranked by what it would actually cost you, and moves through approval to done, with the evidence to prove it.

Behind the platform is a boutique London team: CISSP and CCSP certified, ISO 27001 Lead Implementer and Auditor, NIST CSF practitioners. Advisory and vCISO support are there when you want humans in the loop.

Evidence

Check us before you talk to us

We argue that attestations should be verified rather than trusted. That applies to ours. Everything here is checkable without speaking to anyone.

We audited our own domain

A worked demonstration against penthropic.ai using only public sources, published with the two gaps it found in our own configuration.

What past engagements changed

What was verified, what was found, what changed and over what period. A fixed structure, with at least one number in each.

See what a finding looks like

What the vendor claimed, what we observed, the delta, and the control it maps to. The actual output, before any call.
