In partnership with
In the last ~48 hours, several significant cybersecurity developments have emerged that should shape your weekend posture: Tenable warned of an expanding “AI exposure gap” across cloud and dev environments that undermines security controls; the Radware 2026 Global Threat Report showed a 168 % year-over-year surge in DDoS attacks across network and application layers; the U.S. NSA released updated Zero Trust implementation guidelines aimed at strengthening enterprise architecture; and Indian telecom giant Bharti Airtel launched an AI-focused cyber threat research initiative with Zscaler to protect critical sectors.
These themes underline escalating threat automation, architectural risk, and the need for strategic investment in detection and resilience.

Top-level takeaways this week:
AI & Cloud Exposure ↑ — Tenable flags severe gaps in AI and cloud security posture.
Network & DDoS Activity ↑ — Radware reports dramatic escalation in DDoS and multi-vector attacks.
Architectural Risk ↑ — NSA Zero Trust guidance emphasizes identity and verification controls.
Strategic Public/Private Collaboration ↑ — Airtel and Zscaler initiative targets AI-driven threats to critical infrastructure.
1) Tenable flags a growing AI exposure gap – High
What changed: Tenable’s Cloud & AI Security Risk Report 2026 highlights that 86 % of orgs have critical vulnerabilities from third-party packages and 65 % expose high-value assets via forgotten cloud credentials, coining the concept of an “AI exposure gap” where security teams lag behind rapid adoption.
Why this matters: As AI accelerates both development and attack methods, organizations that fail to integrate exposure management into cloud and AI pipelines risk invisible, high-impact compromises.
2) Radware’s 2026 Global Threat Report – High
What changed: Radware’s threat analysis shows that DDoS attacks targeting layers 3/4 of the network and application layers have surged 168 % year-over-year, emphasizing attack automation and multi-vector disruption strategies.
Why this matters: High-volume DDoS campaigns now combine with stealthy exploit probes, escalating both availability risk and upstream operational costs for cloud and edge services.
3) NSA releases updated Zero Trust Implementation Guidelines – Informational
What changed: The U.S. National Security Agency issued new phased Zero Trust architecture guidelines focused on continuous verification and least-privilege for defense, DoD, and enterprise environments.
Why this matters: Zero Trust remains a strategic control for reducing lateral movement, credential abuse, and implicit trust, critical as identity-centric attacks rise.
4) Bharti Airtel and Zscaler launch AI & Cyber Threat Research Center – Informational
What changed: Bharti Airtel partnered with Zscaler to establish an AI & Cyber Threat Research Center aimed at protecting national critical infrastructure, including banking, energy, and telecom, from AI-powered threat vectors.
Why this matters: AI-driven research and defense collaborations help shift the balance as attackers increasingly leverage AI, and defenders must build equivalent capabilities for detection and response.
Stage | Vector / System | What We’re Seeing |
|---|---|---|
Initial Recon & Exploitation | Automated network attacks (DDoS) | Radware’s report reinforces multi-vector, high-automation probing and disruptions. |
Persistence & Access | AI exposure gaps | Rapid engineering cycles create unnoticed cloud and AI pipeline exposures. |
Strategic Defense | Zero Trust & collaboration | NSA guidance and industry partnerships push architectural resilience and shared threat intel. ) |

🔄 Patch & Hardening
Cloud & AI pipelines: Audit third-party packages and enforce least privilege for cloud credentials; adopt policy-based blocklists for unmanaged artifacts.
Network stack: Increase DDoS protections and automation of mitigation (scrubbing, rate limits) for edge and application layers.
Identity & Access: Start Zero Trust adoption with micro-segmentation, multi-factor auth, and continuous identity verification per NSA guidelines.
🧑💻 People & Monitoring
AI/Dev teams: Alert on unusual dependency changes, orphaned services, and elevated privileges in CI/CD pipelines.
Network ops: Detect volumetric spikes, stateful session exhaustion, and multi-vector probes preceding DDoS peaks.
IAM: Monitor lateral access attempts, conditional auth flows, and policy drift across Zero Trust controls.
📋 Process
Implement change freezes on network controls and IAM policy unless CISO-approved this weekend.
Tabletop (30 min): “AI exposure → identity abuse → DDoS impact.”
🤝 Partners
MSPs/ISACs: Provide centralized threat telemetries and partner with research centers like the Bharti-Zscaler initiative to share emerging attack patterns.
AI exposure signals: Deviations in dependency inventories and cloud metadata logs.
DDoS precursors: Unusual SYN/ACK patterns, irregular BGP announcements, and proxy rate spikes.
Identity anomalies: Unexpected conditional access or token issuance outside standard baselines.
Overall: High for automated, AI-enabled, and network-scale disruptions; Medium-High for identity-centric exposures and architectural drift; Medium for nascent collaborations whose benefits depend on integration speed and scale.
AI exposure gaps are real: Rapid engineering may weaken controls unless visibility is enforced.
DDoS surges require automation: Manual mitigations lag behind today’s attack tempo.
Zero Trust is mission-critical: NSA guidance modernizes identity and access strategies.
Public-private research matters: Collaborations like Airtel-Zscaler help evolve threat detection at scale.
🔄 Verify: AI/Cloud dependency audit completion.
📊 Validate: DDoS mitigation and alert coverage.
💼 Confirm: Zero Trust control baseline deployment.
🔹 Double-check: Monday tabletop — “AI pipeline compromise → identity abuse → mass disruption.”
Final Insight: Attackers are leveraging automation, AI, and infrastructure complexity to compress the distance between vulnerability and exploitation.
To stay ahead, you must bring exposure management, identity verification, and resilient networks onto the same strategic timeline… and do it before next week.
