What are Attack Surface Management services and why they matter

Key takeaways on Attack Surface Management services

•  Attack Surface Management services provide continuous visibility into external-facing assets, helping organisations identify unknown, misconfigured, and forgotten assets before attackers exploit them.
• Most modern attacks begin with exposed infrastructure rather than advanced exploits, making proactive attack surface discovery and risk identification critical for prevention.
• Tata Communications delivers Attack Surface Management as part of its Cyber Threat Intelligence as a Service (CTIaaS), combining global threat intelligence, asset discovery, and expert-led analysis.
• By integrating Attack Surface Management into CTIaaS workflows, enterprises can prioritise remediation based on real-world threat activity, reduce exploitable risk, and strengthen overall cyber resilience.

Attack Surface Management services explained

Continuously reduce exposure across your expanding digital footprint

In a hyper-connected enterprise, your attack surface is constantly changing — cloud workloads spin up overnight, new applications go live, vendors connect remotely, and forgotten assets remain exposed. Every unmanaged asset becomes an open door for attackers.

Tata Communications’ Attack Surface Management (ASM), delivered as part of our Cyber Threat Intelligence as a Service (CTIaaS) portfolio, continuously discovers, monitors, and assesses your external-facing digital assets — helping you identify vulnerabilities before adversaries do.

Why Attack Surface Management matters for modern enterprises

Modern cyberattacks rarely start with sophisticated exploits. They begin with simple, overlooked exposures.

• The invisible perimeter: Unknown internet-facing assets, Shadow IT, and legacy applications that exist outside the security team's radar.
• Infrastructure hygiene: Misconfigured cloud services, expired certificates, open ports, and irregular patch management that leave doors unlocked.
• Access & identity gaps: Weak identity controls—such as lack of MFA or SSO—combined with excessive permissions and poor policy enforcement.
• The extended ecosystem: Weaknesses in third-party postures and poorly configured supply chain integrations that bypass primary defences.

Without continuous visibility, security teams are forced into reactive firefighting — responding only after attackers have already gained a foothold.

Attack Surface Management shifts security left — from response to prevention.

How Attack Surface Management fits with brand monitoring

Brand monitoring identifies how attackers misuse your digital identity. Attack Surface Management reveals the technical weaknesses they exploit to do it.

Together, they provide a complete external risk view — from exposure to exploitation.

What begins as an exposed asset often escalates into brand impersonation, phishing, or data compromise — making Attack Surface Management a critical foundation for effective brand monitoring.

What Tata Communications Attack Surface Management does

Continuous asset discovery

Automatically discovers all external-facing digital assets across:

• Domains and subdomains
• IP addresses and cloud workloads
• Web applications and APIs
• Third-party connected services

No reliance on static inventories or manual inputs.

Exposure & risk identification

Identifies risks that attackers actively look for, including:

• Open ports and insecure services
• Misconfigurations and weak controls
• Outdated software and known vulnerabilities
• Orphaned or forgotten assets

Each finding is contextualised with risk severity and potential impact.

Contextual threat intelligence overlay

Unlike standalone ASM tools, our service enriches asset data with real-world threat intelligence, helping teams prioritise what truly matters.

• Assets targeted by active threat campaigns
• Infrastructure linked to botnets or malicious IPs
• Exploitable exposures seen across global attack patterns

Actionable recommendations

Every insight is paired with clear remediation guidance, enabling security and IT teams to act quickly and confidently.

Why Tata Communications for Attack Surface Management services

Attack Surface Management is most effective when powered by global visibility, intelligence depth, and operational expertise — not just scanning technology.

Built on CTIaaS Intelligence, our ASM capability is embedded within Cyber Threat Intelligence as a Service, combining:

• Intelligence from 60+ integrated threat feeds
• Insights from expert threat hunters
• Network-level visibility across ~30% of global internet traffic

This allows earlier identification of exploitable exposures — often before they are weaponised.

Cloud-native and continuously updated

• Always-on monitoring — not point-in-time scans
• Adapts dynamically as your digital footprint evolves
• No heavy infrastructure or deployment overhead

Integrated with your security ecosystem

• API-driven integration with SIEM and SOAR platforms
• Supports automated workflows for detection and response
• Complements SOC operations without adding noise

Managed by security experts

Our globally distributed SOC teams support:

• Risk validation and prioritisation
• Ongoing tuning and intelligence updates
• Operational guidance aligned to real-world attack behaviour

Key benefits of Attack Surface Management services

• Reduce exploitable risk across your external environment
• Eliminate blind spots created by shadow IT and legacy assets
• Prioritise remediation based on real threat activity, not assumptions
• Strengthen brand protection by reducing technical entry points
• Improve security posture without increasing operational complexity
• Better compliance & risk management through evidence availability & audit support 

Part of a unified cyber resilience approach

Attack Surface Management is delivered as an enhanced capability under Tata Communications’ CTIaaS, which itself is part of our broader Cyber Resilience Services portfolio.

Across the lifecycle, we support:

• Assess – Identify exposure and risk
• Execute – Implement intelligence-led controls
