Penetration Testing for UK Environmental and Climate Tech
CREST-accredited penetration testing for carbon accounting platforms, ESG reporting software, environmental monitoring and compliance data exchanges. We test carbon reporting portals, sensor dashboards, the exchange that carries verified data to auditors and registries, and the multi-tenant boundary between customer organisations. We test your software; we do not verify your emissions methodology.
- Unlimited retesting
- Unlimited pre-retesting
- No hidden fees
“I would highly recommend EJN Labs to any organisation seeking reliable, detailed, and well-managed penetration testing services, particularly for government or enterprise-level projects.”
“There wasn’t another company we could find that could deliver what we needed in the timeframe we needed. The client loved it, and we got instant ROI from the engagement.”
platform types we test on every climate-tech engagement: the carbon reporting portal, the sensor dashboard feeding it, the compliance data exchange to auditors and registries, and the multi-tenant boundary between customer organisations.
What Buyers & Auditors Expect From a Climate-Tech Platform
Independent testing evidence, not a compliance audit. We test the software behind your reporting, not the reporting methodology itself. In our experience, enterprise customers, auditors and assurance providers reviewing a carbon accounting, ESG or environmental-monitoring platform increasingly ask for independent security testing evidence before they trust it with emissions, sensor or compliance data, in much the same way they ask a SaaS vendor for a SOC 2 report.
UK GDPR Article 32. Carbon reporting, sensor and compliance-exchange platforms hold personal data too: customer contacts, user accounts and often the personal data of the people submitting or verifying emissions data. Article 32(1)(d) requires a process for regularly testing, assessing and evaluating the effectiveness of your security measures. It does not name penetration testing as the method, but a test is the most direct evidence that your controls work.
Why buyers ask about SOC 2. Enterprise customers evaluating a climate-tech platform often ask about security testing in due-diligence questionnaires, and auditors commonly expect a recent third-party test before signing off a SOC 2 report. The AICPA criteria list penetration testing as one example of an evaluation (CC4.1) rather than a requirement, so the test is how you evidence the control, not a box on its own.
Who we test for. Carbon accounting and ESG reporting software vendors, environmental and emissions-monitoring platforms, sustainability data and compliance-exchange operators, and the sensor or IoT vendors supplying them. We test your software and its data flows; verifying your emissions methodology or ESG scoring sits with your own assurance provider, not with a penetration test. See our IoT penetration testing and multi-tenant SaaS penetration testing pages.
SCOPE
What We Test in Environmental & Climate Tech
Carbon Reporting & ESG Portals
Emissions data entry, calculation-trigger endpoints, and report generation and export. Access control around draft versus submitted reports, and IDOR across customer accounts and reporting periods.
Environmental Sensor Dashboards
Air, water and emissions-monitoring sensor dashboards. Device enrolment, per-device identity and keys, and whether a compromised or spoofed sensor can feed false readings into a customer’s compliance report.
Compliance Data Exchange
API and file-based feeds moving verified emissions or compliance data between your platform, auditors, registries and regulators. Object-level authorisation, message integrity and replay protection across the exchange.
Multi-Tenant Customer Separation
Row-level security and tenant checks so one customer organisation cannot read, change or export another’s emissions or compliance data through the app, the API or scheduled reports.
Assessor & Auditor Access
Time-limited external assessor and verifier accounts reviewing a customer’s submitted data. Delegated read versus write permissions, and whether one assessor account can reach another client’s records.
Cloud Infrastructure & Data Residency
AWS, Azure and GCP configuration for emissions, sensor and compliance data. Encryption at rest, IAM scoping, audit logging and data-residency controls.
External Perimeter & Remote Access
External-facing infrastructure supporting engineering, data-science and back-office functions: VPN gateways, exposed management interfaces and cloud consoles. CREST methodology identifies exposed services, weak authentication and unpatched systems reachable from the internet.
Phishing Defence
Targeted phishing simulation against data, sustainability and finance staff, using climate-tech-aware lures such as fake auditor requests and supplier-payment fraud.

FAQ
Frequently Asked
What does a climate-tech test look at that a standard web app test does not?
Tenant separation between customer organisations, sensor and device identity so readings cannot be spoofed, the integrity of the exchange carrying verified data to auditors and registries, and delegated assessor access that must not reach another client’s records.
Do you verify that our emissions calculations or ESG methodology are correct?
No. We test the security of the software: who can read, change or export data, and whether the platform enforces the boundaries it claims to. Verifying your emissions methodology or ESG scoring sits with your own assurance provider or auditor, not with a penetration test.
Which climate-tech organisations do you test for?
Carbon accounting and ESG reporting software vendors, environmental and emissions-monitoring platforms, sustainability data and compliance-exchange operators, and the sensor or IoT vendors supplying them.
Can you test our platform before a SOC 2 Type II audit?
Yes. We provide a CVSS-scored report and letter of attestation your auditor can review as evidence under CC4.1, alongside your other Trust Services Criteria evidence.
Can you test a Supabase or Firebase-backed carbon accounting app before we onboard enterprise customers?
Yes. We test the row-level security policies, tenant and role claims, and the server-side functions and service keys that could bypass them. See our Supabase and Firebase pages.
How do you handle live customer, emissions and sensor data during testing?
We ask for a non-production environment with synthetic or anonymised customer, sensor and reporting data wherever possible. Production testing only goes ahead with your explicit approval and a restricted scope.
Can you test the assessor or auditor portal without exposing other clients’ submitted data?
Yes. We create separate assessor test accounts scoped to a single test client, then attempt to reach another client’s data through the app, the API, exports and shared reports.
What’s in the report?
Executive summary (board-ready), technical report with CVSS 3.1 scores, reproduction steps, screenshots, specific remediation guidance, and a 60-minute walkthrough call. Letter of attestation issued after free retest.
Do you sign NDAs?
Yes. We sign client-supplied NDAs as standard. Engagement data is protected under our ISO 27001 (BSI-audited) information security management system.
How quickly can you start?
From signed scope to active testing in 24 hours where required. Standard pipeline is 3-5 business days from initial scoping call to test start.
Are your testers UK-based and what certifications do they hold?
Every engagement is performed by vetted UK-based CREST-certified testers matched to your engagement based on security clearance, compliance scope, and sector specialism. Testers hold CREST certifications relevant to their discipline (CRT, CCT APP, CCT INF, CCSAM).
