Rethinking Enterprise Security at the Opening of 2026

By early 2026, enterprise security feels very different from just a few years ago. AI agents are now embedded across core workflows, critical vulnerabilities have emerged across widely deployed frameworks with the highest possible severity ratings, and federal standards such as the Cybersecurity Performance Goals 2.0 have reset baseline expectations for security maturity.

Risk now stretches across identity systems, AI automation, software supply chains, and the relatively small set of dominant platform providers that support the majority of enterprise infrastructure. These dependencies reshape how organizations think about resilience, continuity, and risk ownership.

Netizen’s viewpoint entering 2026 is that four themes define the landscape: AI adoption, identity-centric security, concentration risk, and outcome-driven security management. Each demands deliberate focus from leadership.


AI has become an operational dependency

During 2025, AI moved directly into daily business functions. Security teams have begun using AI to enrich events, triage alerts, and analyze exposure. At the same time, adversaries are using AI to generate phishing content, craft malware, impersonate real people, and create synthetic identities. Trust in traditional communication channels has weakened as convincing deepfakes and automated interactions become routine.

Security research points to growing use of AI governance and control layers that restrict what AI agents can do inside enterprise environments. This reflects the increasing reality that AI-driven systems often possess API credentials, privileged data access, and the ability to perform business or administrative actions autonomously.

AI usage now requires the same level of policy oversight, auditability, and monitoring as other privileged enterprise systems.


Identity now defines the security boundary

Identity remains the most direct point of entry into enterprise systems. With AI agents, automation pipelines, and microservices now authenticating through the same identity platforms as human users, the blast radius of a compromised identity has grown significantly. Mis-scoped privileges, long-lived credentials, and opaque service-to-service delegation chains expand the opportunity for attackers.

Organizations benefit from treating human identities, service accounts, and AI agents as equally critical. Access entitlements should be as narrow as operations allow, expirations should be enforced where practical, and authentication telemetry should feed directly into detection and response.

For security operations teams, this means identity behavior analytics and delegated access visibility sit at the center of monitoring programs.


Late-2025 zero-days revealed systemic fragility

Two late-year vulnerabilities demonstrated how dependent organizations have become on a small number of core platforms.

CVE-2025-20393 affected Cisco Secure Email Gateway and Cisco Secure Email and Web Manager through an input validation flaw that allowed unauthenticated remote command execution with root-level privileges. It received a maximum CVSS score of 10.0, reflecting the potential severity of compromise at a gateway layer that processes sensitive business communications. Public reporting associated exploitation with a China-nexus actor targeting specific appliance configurations exposed to the internet.

CVE-2025-55182, also known as “React2Shell,” impacted React Server Components and downstream frameworks such as Next.js due to unsafe handling of serialized data in the Flight protocol. A single crafted HTTP request could execute arbitrary Node.js code, again with a CVSS score of 10.0. The exposure affected common default configurations, which amplified the scale of potential risk across production environments.

These two incidents show that security design must elevate email infrastructure, popular development frameworks, core identity platforms, and administrative interfaces into a distinct tier of critical assets that receive accelerated monitoring and remediation.


Concentration risk has become strategic

Most organizations rely heavily on a limited set of cloud providers, SaaS ecosystems, and security platforms. This creates operational simplicity but also concentrates systemic risk. A service disruption or security incident affecting one dominant platform can produce cascading effects across the customer base.

At the same time, misinformation regarding basic cyber hygiene continues to circulate on social channels, undermining public confidence in controls such as multi-factor authentication and password vaults. This environment benefits adversaries who rely on social engineering and psychological pressure.

Security planning increasingly includes tabletop exercises focused on prolonged outages, identity provider degradation, and SaaS failure scenarios. Documented fallback communications paths, secure break-glass workflows, and continuity-mode playbooks significantly reduce chaos when external services become unavailable.


Cybersecurity Performance Goals 2.0 set new expectations

The release of Cybersecurity Performance Goals 2.0 aligned with NIST Cybersecurity Framework 2.0 and placed stronger emphasis on measurable outcomes across user and device security, governance, incident response, and data protection.

Leadership teams now look for demonstrable risk reduction rather than simple control inventories. Metrics such as incident dwell time, phishing click-through rates, recovery readiness, and patch latency are becoming more influential in governance discussions.

For environments tied to public sector missions, critical infrastructure, or federal oversight, alignment with CPG 2.0 is becoming a de-facto baseline expectation. Netizen’s approach has long emphasized measurable security outcomes, so this shift aligns with how we design programs and evaluate maturity.


A practical reset for early-2026 security programs

Organizations benefit from beginning the year with a precise map of their identity ecosystem and AI usage. This includes identity providers, trust boundaries, delegated applications, persistent credentials, and the AI agents or automation systems capable of submitting privileged requests. Reducing standing privileges, binding access to shorter time windows, and expanding identity-centric monitoring meaningfully improves resilience.

AI systems should be treated as operational technology rather than experimental tools. That means identifying where AI is already embedded in business processes, how it interacts with sensitive data, and what controls exist around inference logging, prompt history, and agent decision-making. Guardrail technologies are increasingly being evaluated to mediate and supervise AI-initiated actions.

Keystone platforms such as email gateways, identity platforms, React and Next.js-based applications, and internet-exposed administration layers benefit from accelerated hardening, scanning, and remediation cycles. For high-impact vulnerabilities like CVE-2025-20393 and CVE-2025-55182, teams should pair patching with targeted detection content across SIEM, endpoint, and network telemetry.

Concentration risk planning should move from concept to documented practice. Even if full provider diversity is not feasible, organizations gain value from clear emergency workflows that assume temporary loss of a primary SaaS, cloud, or identity service.

Finally, internal programs can be benchmarked against Cybersecurity Performance Goals 2.0 and NIST CSF 2.0. These frameworks provide a practical structure for assessing whether key controls are operating effectively across governance, identity, data, and response.


Netizen’s role in 2026

The opening of 2026 marks a period of accelerating threat activity, expanded AI-driven automation, and rising oversight expectations across both public and private sectors. Security programs that adapt to identity-centric design, AI governance, critical platform exposure management, and concentration-risk planning will be better positioned to manage uncertainty.

Netizen partners with enterprises, government agencies, and critical infrastructure operators to mature security programs, stabilize operations, and improve measurable resilience.
