Gartner: Identity-First Security Push — Netscout Systems Joins Layered Data-Governance Stack

Identity-first security and Netscout’s place in a layered data-governance push

Gartner’s 2026 cybersecurity trends report is spotlighting an industry pivot toward identity-first defenses and lists Netscout Systems among a cohort of vendors building layered internal data-governance stacks. The analyst firm says an estimated 75% of enterprise intrusions now involve compromised credentials rather than traditional software exploits, a shift that undermines the effectiveness of legacy perimeter controls and elevates the need for internal visibility and governance.

The report singles out post-quantum cryptography migration and AI agent identity governance as two of six forces reshaping enterprise security, placing companies such as Netscout alongside SailPoint, Commvault and Confluent in efforts to create multi-layered controls. Netscout’s network and security visibility capabilities are positioned to play a role in that stack by helping organisations detect credential abuse, lateral movement and exfiltration inside the perimeter, and by providing forensic data that supports policy enforcement and incident response.

The identity-first framing and Gartner’s emphasis on layered internal controls compel a broader rethink of security architectures, the report says, with vendors adapting products and integration patterns to prioritise identity telemetry, cryptographic agility and data governance. For network-centric security providers like Netscout, the moment stresses interoperability with identity platforms and the need to support new cryptographic standards as organisations plan migrations away from legacy algorithms.

Regulatory pressure and sovereign-cloud demand

Gartner also forecasts sovereign-cloud IaaS spending of about $80 billion in 2026 as Europe, the Middle East and Asia–Pacific accelerate data-residency mandates. Complementing market drivers, U.S. Cybersecurity and Infrastructure Security Agency guidance is directing federal agencies to procure only quantum-resistant products across cloud and endpoint categories, making cryptographic agility a baseline procurement requirement.

Education and practical planning for post-quantum threats

Quantum Secure Encryption Corp. is responding with a free webinar titled “The Post-Quantum Shift: What Changes? What Fails? What to Do Now?” scheduled for Feb. 17, 2026, aimed at IT leaders and security teams. The briefing targets practical planning to mitigate “harvest now, decrypt later” threats and underscores vendor and customer urgency to move from theoretical awareness to concrete migration and governance steps. Registration is required.
