Penetration Testing for UK Postal, Parcel and Courier Services
CREST-accredited penetration testing for UK postal operators, courier and last-mile delivery companies, and the fulfilment, warehouse and locker-network providers behind them. We test parcel tracking and customer portals, warehouse and fulfilment platforms, and depot and driver apps, with UK GDPR evidence for the addresses and delivery data every parcel carries. Redirection, proof-of-delivery and depot-permission boundaries checked throughout.
- 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.”
trust boundaries we test on every tracking, depot or locker platform: who can see a delivery address, who can redirect a parcel, and whether a proof-of-delivery record can be tampered with.
What UK GDPR, PCI DSS & Retail Buyers Expect
UK GDPR. A tracking number, delivery address and contact number are personal data, and a public-facing tracking page that reveals more than the reference number it was given is a common source of address exposure. 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. UK GDPR Article 32.
PCI DSS. Platforms that take card payments for postage, shipping labels, redelivery fees or locker access sit inside PCI DSS 4.0.1. Requirement 11.4.2 and 11.4.3 call for internal and external penetration testing at least once every 12 months and after significant change, and 11.4.1 expects a documented testing methodology. PCI Security Standards Council.
Redirection and delivery-scam risk. A parcel redirected to an address the sender never chose, whether through a compromised account, a manipulated hold-for-collection request or a spoofed rescheduling message, is a well-known abuse pattern in last-mile delivery. We test the controls around an address or redirection change: what verifies the request, what gets logged, and whether a customer is notified before a parcel moves.
Who we test for. National and regional postal operators, courier and last-mile delivery companies, click-and-collect and locker-network operators, and the fulfilment or third-party logistics (3PL) providers and marketplace integrations behind them. Depot and driver-facing apps are covered under our mobile application penetration testing methodology.
SCOPE
What We Test for UK Postal, Parcel & Courier Services
Parcel Tracking & Customer Portals
Public tracking-by-reference pages and logged-in customer accounts. IDOR across tracking numbers and delivery addresses, account-to-account data leakage, and whether a tracking reference alone can expose more than its own parcel.
Fulfilment & Warehouse Management
Warehouse management systems (WMS), pick-pack-ship workflows and shipping-label generation. Multi-client and multi-tenant separation for 3PL operators handling several retailers on one platform, and inventory or consignment-record tampering.
Depot & Driver Apps
Driver rounds, proof-of-delivery capture and depot-management apps. Depot-to-depot and driver-to-driver permission separation, round-reassignment authority, and whether a delivery photo or signature can be altered after capture.
Redelivery, Hold & Locker Networks
Redelivery scheduling, hold-for-collection requests, and pick-up-drop-off (PUDO) locker networks. Address and redirection-change verification, and PIN or QR-code replay against locker access points.
Carrier, Marketplace & EDI Integrations
APIs and EDI feeds behind marketplace and retailer integrations, interline agreements with other carriers, and label-generation plugins. OWASP API Top 10 testing for object-level authorisation and cross-retailer data leakage on shared platforms.
Cloud Infrastructure
AWS, Azure and GCP configuration for tracking, address and payment data. Encryption at rest, IAM scoping, audit logging and tenant boundaries where a single platform serves several retailer or courier brands.
Depot, Sortation & Corporate Networks
Segregation between sortation-machinery control systems, depot floor networks and corporate IT. Active Directory attacks and the boundary between managed office devices and warehouse or sortation equipment.
Phishing Defence
Targeted phishing simulation against depot, finance and customer-service staff, using courier-aware lures such as spoofed redelivery-fee texts and driver-impersonation messages.

FAQ
Frequently Asked
Which regulations apply to a postal or courier platform?
There is no single postal-sector penetration testing mandate. UK GDPR Article 32(1)(d) requires you to regularly test the effectiveness of your security measures for the address and contact data every parcel carries, and PCI DSS 4.0.1 applies once your platform takes card payments for postage, labels or locker access. Beyond that, in our experience, retailer and marketplace customers commonly run their own supplier due diligence and ask for independent testing evidence directly.
Can you test our tracking portal without exposing real customer addresses?
Yes. We test against a non-production environment with synthetic tracking numbers, addresses and account data wherever possible, and we scope any production testing to avoid touching live customer records.
Do you test for parcel redirection or delivery-scam risk?
Yes. We test what verifies an address or redirection change, whether the change is logged, and whether the customer is notified before a parcel is redirected or a hold-for-collection request is actioned, covering both account-based changes and spoofed rescheduling messages.
Can you test our driver or depot app, including proof-of-delivery capture?
Yes. We test the driver app’s round data, proof-of-delivery photo or signature capture, and depot-management functions, checking device storage of delivery evidence and whether a captured proof-of-delivery record can be altered after the fact.
Do you test click-and-collect locker networks and PUDO points?
Yes. Pick-up-drop-off (PUDO) locker networks, including PIN or QR-code access, hold-duration limits, and the boundary between the courier’s locker-management platform and the retailer or marketplace that books a slot in it.
Can you test our warehouse management system’s integration with a retailer’s Shopify or Magento checkout before peak season?
Yes. We test the API or plugin integration between your WMS and a retailer’s storefront, including our dedicated Shopify and Magento methodologies, and we can prioritise scoping around a peak-season go-live date if you tell us during the scoping call.
Which postal, parcel and courier organisations do you test for?
National and regional postal operators, courier and last-mile delivery companies, click-and-collect and locker-network operators, and the fulfilment or third-party logistics providers and marketplace integrations behind them.
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).
