Cybersecurity Services

DXC Cybersecurity is a comprehensive, integrated security solution delivered by 3,200+ security professionals worldwide. Unlike traditional security approaches that layer disconnected tools like SIEM, EDR and network monitoring — creating alert fatigue and blind spots — DXC orchestrates your security intelligence so identity, threat detection and data protection inform one another. This integrated architecture eliminates noise and catches what actually matters. Our approach combines zero trust principles, AI-powered threat hunting and data-centric protection across cloud, SaaS, and on-premises systems, delivering resilience that grows with your business transformation.

Alert fatigue is the enemy of security effectiveness. Most organizations receive hundreds of thousands of alerts daily, but only a fraction represent real threats. DXC's AI-powered Security Operations Center (SOC) uses agentic AI to continuously process millions of alerts and autonomously investigate indicators of compromise, abnormal behavior and attack chains. This reduces response time by up to 70% while filtering out noise. Our integrated intelligence platform merges data from 30+ industry-leading tools — Microsoft, CrowdStrike, Splunk, Palo Alto Networks — into a single, context-aware view. By making identity governance, threat detection and data protection work together, we surface the threats that matter and eliminate false alarms.

Enterprises working with DXC typically achieve three primary outcomes: first, measurably faster threat detection and response — many clients reduce mean time to detect (MTTD) by 40-50% and response time by up to 70%. Second, reduced security overhead and burnout — your security team focuses on strategic threats, not alert triage. Third, compliance and risk acceleration — our proven operating model moves organizations through risk assessments, zero trust implementations and regulatory compliance faster than traditional approaches. Additional benefits include improved operational efficiency through integrated architecture, faster cloud migrations and digital transformations because security enables rather than blocks business initiatives, and demonstrable compliance across frameworks like HIPAA, PCI-DSS, SOX and NIST.

DXC addresses four critical cybersecurity challenges enterprises face today.

• First, alert and tool sprawl: organizations accumulate 10-15 security tools creating siloed intelligence and blind spots; we integrate them into coherent architecture.
• Second, reactive versus proactive security: most organizations detect breaches months after compromise; we shift to proactive threat hunting using agentic AI to catch attacks before they succeed.
• Third, security as a speed bump: legacy security processes block cloud migrations, remote work and AI initiatives; our adaptive governance accelerates business transformation safely.
• Fourth, static security postures: threat landscapes evolve daily, but many security programs remain rigid; we build continuous learning and improvement into operations.

These challenges collectively create risk, cost, and operational friction that DXC eliminates through integrated, intelligent cybersecurity service offerings.

The security environment has fundamentally changed. Perimeter-based security is dead — threats originate inside your infrastructure, your supply chain and your trusted partners. Zero trust, which treats every access request as potentially malicious regardless of source, is no longer optional.

Additionally, the threat landscape accelerates faster than static security programs can respond. Enterprises that stay ahead continuously learn from threats, adapt controls, update detection rules and improve architecture in real-time. Agentic AI now enables this continuous evolution at scale.

Finally, regulatory expectations have tightened: NIST CSF, SEC cybersecurity rules and industry-specific frameworks demand demonstrable, integrated security. Organizations delaying zero trust implementation, cloud security modernization or AI-driven threat hunting are falling behind competitors and regulators. DXC's experience securing some of the world's most complex enterprises — we provide cybersecurity industry solutions for organizations ranging from financial institutions to government agencies — provides the operating model and partnerships needed to accelerate security transformation now.

DXC's data-centric security approach follows your data everywhere — cloud, SaaS and on-premises systems. We classify all sensitive data at the point of creation, apply consistent encryption standards across all environments, and enforce access rules dynamically based on user, device and context. This matters because 90% of successful attacks rely on stolen credentials; attackers often don't break in — they log in with compromised access.

By combining data governance with identity analytics, behavioral threat detection and zero trust access controls, we catch credential-based attacks that perimeter and endpoint tools miss. Our integration with Microsoft Purview, AWS data protection services and Google Cloud DLP ensures policies are consistent and enforceable across all platforms. We also provide continuous data auditing and compliance reporting against HIPAA, PCI-DSS, SOX and GDPR, so you maintain control over sensitive data regardless of where it lives or who accesses it.

Enterprises should evaluate these key criteria:

1. Depth of expertise: Does the provider have proven experience securing enterprises at your scale and in your industry? Look for customer references and case studies, not marketing claims. 
2. Integration capability: Can it coordinate best-of-breed tools into a coherent architecture, or does it pitch proprietary products? 
3. Operational maturity: Does the provider have an established methodology for advisory, implementation and continuous operations, or does it offer ad-hoc consulting? 
4. Strategic partnerships: Does it maintain relationships with leading vendors (cloud providers, endpoint tools, SIEM, threat intelligence) to ensure your investments remain current? 
5. Proactive versus reactive posture: Does the provider emphasize threat hunting and continuous improvement, or just faster incident response?
