Zero Trust Data Mesh

Think of traditional security as a bouncer at the front door: verify once at entry, then trust everything inside. Zero Trust Data Mesh flips that model. It treats every access — whether from your office network or a coffee shop — as untrusted until proven otherwise, and it makes those decisions at the data level, not the network level. A user might be legitimate, but are they on a healthy device? Is their behavior normal? What does threat intelligence say about their location right now? The system weighs all of this before deciding to grant, restrict or isolate a session. The result: data stays protected no matter how your organization grows, where employees work or which cloud platforms you add.

The 90 percent of attacks that succeed do so using stolen credentials from legitimate employees. A compromised account on an old laptop can still appear as a trusted user on your VPN. Zero Trust Data Mesh changes the equation by adding layers of verification beyond just "is this the right password?" It tracks device health, monitors for unusual behavior, checks threat intelligence and can instantly isolate a session if something looks wrong — all while the user continues their work through a verification prompt rather than a hard block. This layered approach for risk-based authentication catches lateral movement inside your network before attackers can access sensitive systems or exfiltrate data.

Many organizations buy an identity tool here, a cloud security tool there, an endpoint tool elsewhere. The problem: they do not communicate. One system sees the user is logged in from Tokyo at 3 a.m., another tool sees they are on a managed device, a third tool sees them accessing databases. None of these systems talk to each other, so access gets granted.

Leading vendors in the zero trust access control solutions space let companies do things differently. In DXC's case, we build architectures where these tools share intelligence. Identity data informs data protection decisions. Threat signals reshape risk calculations. Compliance rules become active policy, not a checkbox. This orchestration, combined with 30 years managing enterprise security at scale, means you get faster deployment and smarter decision-making than bolting together best-of-breed tools alone.

The complexity most organizations struggle with is fragmentation: different access rules for different systems, compliance teams pulling logs from five places, security teams responding to incidents across disconnected tools. One hospital network we help manages 50,000 user accounts across on-premises legacy systems, multiple cloud providers and dozens of SaaS applications. With centralized policy, they enforce one rule: Patient records require encryption, logging and step-up authentication from any unmanaged device. That rule applies everywhere automatically. Audits become faster because evidence is consolidated. Incident response becomes faster because all systems are talking. And your security team stops spending time managing exceptions and starts focusing on strategy.

Industry research shows 81 percent of enterprises expect to adopt some form of Zero Trust by the end of 2026. The driver is not a single trend; it is a convergence: permanent remote work, cloud sprawl that traditional firewalls cannot protect and regulatory mandates. For most organizations with sensitive data, this is now table stakes. The timing question for your business is not whether you need to move, but how quickly you will move to a  Zero Trust access control model.

Traditional compliance relies on evidence scattered across systems: some in your identity provider logs, some in your data warehouse, some in your firewall. Auditors have to trust your manual compilation. With DXC Zero Trust Data Mesh, you give regulators what they actually want: proof that sensitive data is protected consistently. Every access decision gets logged in one place. Policy changes get enforced everywhere automatically. When an auditor asks whether you can prove customer data is encrypted and requires step-up authentication, you show a comprehensive audit trail, not a collection of separate reports. This consolidated view reduces the friction in compliance cycles and gives your audit team clear evidence to defend controls.

You probably already have Microsoft, Okta, Idira or other security investments in place. DXC does not ask you to replace them. Instead, we integrate them into an architecture that makes them work together. Microsoft Entra becomes your identity backbone for identity and access management (IAM). Zscaler handles cloud access. Idira protects high-risk identities. Your cloud provider (AWS, Azure, Google Cloud) remains your infrastructure layer. Each tool keeps doing what it does well, but now they feed signals to each other instead of operating in isolation. We can customize this architecture for your industry (financial services needs different policies than healthcare), thanks to our decades of experience in major sectors, then manage the whole ecosystem 24/7. You leverage your existing investments while gaining the orchestration and operations you have been missing.

Start with execution track record. Has the vendor deployed this 30+ times or three times? Can they genuinely handle complexity — or will your implementation team end up doing most of the work? Ask about operations. Can they run 24/7 monitoring and incident response, or do they hand you a solution and wish you luck? Dig into their architecture approach. Do they integrate best-of-breed tools intelligently, or do they push proprietary solutions? Test their understanding of your industry. Regulatory requirements for healthcare differ significantly from financial services. Finally, evaluate their model holistically. Can they advise on strategy, implement, operate ongoing and continuously improve? DXC ticks these boxes because we have been securing major organizations for three decades, not just since the Zero Trust trend began.
