Attack Surface reduction
Cube Cyber's attack surface reduction service discovers what your organisation actually exposes to the internet, domains, services, cloud assets, credentials and the forgotten infrastructure nobody owns, then systematically shrinks it. Attackers choose targets by what they can see; this service makes sure you see it first, and that there is less of it every quarter.
Map Our Attack Surface
Attack surface problems are accumulation problems:
The classic trigger is a discovery that should not have been possible, a forgotten service found by a tester, a researcher or an attacker. Better triggers come earlier: after mergers and acquisitions, when you inherit an unknown estate; during cloud and SaaS growth, when exposure creation is decentralised; and before threat actors do their reconnaissance for you. It also sharpens everything downstream, penetration tests scope better, vulnerability management covers more, and monitoring watches the assets that actually exist.
Core capabilities & deliverables
External attack surface discovery
Comprehensive mapping of your internet-facing estate, domains, subdomains, IP ranges, services, certificates and cloud assets, built the way attackers build it, from the outside, with no reliance on your asset register being right.
Shadow and unmanaged asset identification
The high-value core of the exercise: the assets discovery finds that your inventory does not contain, forgotten servers, orphaned cloud tenancies, legacy services and vendor-deployed infrastructure, each assigned an owner or a decommission date.
Exposure assessment
Analysis of what the discovered surface reveals, unnecessary services, risky configurations, outdated platforms and unintended data exposure, prioritised by exploitability and consequence.
Credential and data exposure monitoring
Identification of leaked credentials and exposed organisational data in breach corpuses and public sources, feeding password resets, MFA enforcement and access review before someone else uses them.
Systematic reduction
The point of the exercise: decommissioning, consolidation, service hardening and exposure-by-default policies that shrink the surface, tracked quarter over quarter, less to attack, less to defend, less to pay for.
Continuous monitoring
Ongoing discovery so new exposure is caught in days rather than at the next annual review, integrated with our vulnerability management pipeline and, where engaged, our 24/7 SOC.
The service runs as a cycle rather than a one-off:
Discover
External reconnaissance across domains, infrastructure, cloud and data sources, establishing the real perimeter.
Attribute
— Match discoveries to owners and systems, and separate the known from the shadow, the step that turns a list into accountability.
Reduce
Decommission, consolidate, harden and restrict, prioritised by risk, with changes flowing through your normal change management.
Monitor
Continuous watch for new exposure, with alerts routed into the same ownership model, so the surface stays shrunk.
The service supports ISO 27001 asset management and ASD Essential Eight objectives, sharpens SOCI and CIRMP asset obligations for critical infrastructure operators, and integrates with our penetration testing, given testers the true scope, and vulnerability management, giving the pipeline complete coverage.

Everything about your organisation an attacker can reach or learn from outside: internet-facing systems and services, cloud assets, applications, certificates, and the human layer, exposed credentials, leaked data and what your public footprint reveals. If it can be discovered, probed or abused without credentials, it is surface.
Scanning assesses the assets you point it at; attack surface discovery finds the assets in the first place, including the ones your register has never heard of. They are sequential: discovery establishes what exists, scanning and testing assess it. Most organisations run the second without the first, and their scanners dutifully ignore the forgotten server that gets them breached.
Enough to matter. It is routine for discovery to surface assets the organisation cannot immediately attribute, forgotten subdomains, legacy services, cloud tenancies from finished projects, and the unknown portion is disproportionately risky precisely because nothing unknown is patched, monitored or defended.
The first discovery is the revelation; the ongoing monitoring is the value. Attack surface changes with every deployment and signup, so mature programs run continuous discovery with quarterly reduction reviews. A one-off mapping is still worthwhile, it just starts ageing immediately.
Yes, and M&A is one of the strongest use cases: discovery scoped across acquired entities reveals the estate you actually inherited, before integration connects it to yours. Several forms of the service exist purely for due diligence, mapping a target's external exposure before the ink dries.
Reduce it, and the service carries that through: every discovery gets an owner, a decision, keep and harden, consolidate, or decommission, and a tracked outcome. The quarterly measure of success is simple: fewer exposed services, fewer unknowns, shorter time between new exposure appearing and being caught.
The opposite is the goal. Discovery output arrives triaged and prioritised, most findings resolve as decommissions rather than projects, switching something off is the cheapest security control there is, and the reduction plan is sequenced to your capacity. Teams typically find the program removes more from their worry list than it adds to their work list.
