Attack Surface Management for Retailers: Discovering What Attackers Can See
A typical mid-sized UK retailer's internet-facing attack surface includes: a primary e-commerce site and mobile app; a separate B2B trade portal; a store management system with external access; multiple APIs connecting to payment processors, logistics providers, and inventory systems; a loyalty scheme platform; dozens of third-party scripts on the e-commerce site; and various shadow IT deployments that IT teams may not even know about. Attackers can see all of this. The question is whether you can see it as clearly as they can — and whether you know which components are vulnerable.
The average mid-sized UK retailer has 47 internet-facing assets that IT teams are unaware of — shadow IT, forgotten test environments, and third-party integrations.
What Attack Surface Management Reveals for Retailers
External attack surface management (EASM) continuously scans the internet-facing digital footprint of a retail organisation — discovering all external-facing assets, assessing their security posture, and identifying vulnerabilities before attackers do. For retailers, typical findings include: forgotten test or staging e-commerce environments that are not maintained or patched; development systems accidentally exposed to the internet; misconfigured cloud storage buckets containing customer or product data; e-commerce APIs with authentication weaknesses; subdomains pointing to deprecated services that can be hijacked; and third-party integrations with known vulnerabilities in their software versions. These findings are invisible to internal security teams who only scan what they know about — EASM finds everything.
Hadrian: Continuous Attack Surface Management for Retailers
Hadrian, deployed by Kyanite Blue, provides continuous external attack surface management for retail organisations. Unlike periodic penetration testing that provides a point-in-time snapshot, Hadrian continuously monitors the retail organisation's internet-facing footprint — alerting when new assets appear, when existing assets develop new vulnerabilities, or when third-party components are compromised. For e-commerce retailers who deploy frequent site changes and third-party integrations, this continuous visibility is essential — a new vulnerable plugin deployed on a Wednesday can be discovered and remediated before the weekend trading peak. Hadrian's retail-specific asset discovery includes e-commerce sub-systems, payment integrations, loyalty platforms, and third-party script inventory.
