Attack Surface & Exposure Assessment
Fortura’s Threat & Attack Surface Assessment uses open-source intelligence (OSINT) to identify externally observable exposure across systems, identities, and services, then assesses how real-world threats could exploit that exposure in the context of your business.
Attackers don’t start from inside your network, they start from what they can see.
Publicly accessible information, exposed services, misconfigurations, and digital footprints provide the foundation for most modern attacks. When this exposure is not understood, organisations often misjudge both likelihood and impact of compromise.
An OSINT-driven attack surface assessment provides visibility into what is already exposed, before an attacker exploits it.
Understand externally visible exposure from an attacker’s perspective across domains, certificates, services, and leaked credentials. De-duplicate noisy scan output so defenders see what is reachable, attributable, and worth fixing first.
Identify attack paths derived from real, observable data such as DNS history, cloud metadata, and public code. Ground discussion in evidence your red team and SOC can replay instead of hypothetical architecture diagrams only.
Assess threat relevance based on how exposure could be exploited, using externally visible evidence and realistic attack paths instead of assumptions alone. Tie each finding to plausible tradecraft so prioritisation holds up when challenged by engineering leads.
Apply business context to distinguish critical risk from background noise so teams fix what changes outcomes for customers, revenue, and safety. Map exposure to revenue lines, regulated data, and uptime commitments so investment cases write themselves.
Focus remediation on exposure that materially increases attack likelihood, including paths where credential abuse, control chaining, or third-party trust amplifies impact. Close the smallest set of doors that cut the highest-likelihood intrusion stories.
Join us for results-driven collaboration and growth.
Expanding cloud services, identities, and integrations require attacker- centric visibility that extends beyond asset inventories and validates real- world exposure.
We combine passive discovery with your authorised asset sources so unknown hosts, shadow SaaS, and stale DNS do not hide in plain sight. Everything is tied back to ownership and business relevance.

This report examines the cyber resilience priorities shaping 2026, drawing on current threat intelligence, official cyber reporting, and Fortura's advisory experience.
Geopolitical cyber risk is no longer confined to governments and defence agencies. Global conflict, nation-state activity, hacktivism, and supply chain disruption can change the cyber risk environment for private organisations across every sector.
Explore why CTEM is becoming essential for organisations seeking a more proactive and risk-informed security posture.
AWS, Azure, and Google Cloud are not secure by default. Understanding the shared responsibility model, where cloud security gaps commonly appear, and what a cloud security posture assessment should cover is essential for any organisation running workloads in the cloud.
How employees using unapproved GenAI tools are exposing sensitive data, creating governance blind spots, and making shadow AI one of the most pressing cyber risk priorities for security and business leaders.
Machine identity security is critical as service accounts, API keys, cloud workloads, DevOps pipelines, and AI agents multiply cyber security exposure across environments. Explore practical strategies to reduce machine identity risk and protect your infrastructure.
The MITRE ATT&CK Framework is one of the most powerful tools in a security team's arsenal — but only if you know how to use it.
Master cyber risk reporting to board with practical strategies for clear, relevant, and actionable narratives that drive informed decision-making.
