Change is one of the few constants in the rapidly evolving cloud networking industry. 2024 brought innovations in GenAI, a renewed emphasis on resiliency and security, and new partnerships and integrations across the ecosystem. In this blog series, Aviatrix leaders will discuss what cutting-edge innovations and rising challenges in cloud networking and security they’re seeing come into focus in 2025. See previous blog posts on cloud networking and security in 2025 here.

John Qian is the Chief Information Security Officer at Aviatrix. In his previous role, he served as Zoom’s Head of Security Architecture. His team created one of the industry’s most mature security programs while effectively supporting Zoom’s dramatic business growth during the pandemic. Here are the new challenges and defense measures in cloud security that John is taking on in 2025.

 

New Blind Spots Create New Challenges

The future of cloud security in 2025 and beyond will be shaped by the rapid acceleration of multicloud and hybrid environments, presenting significant challenges for DevOps, network, and security teams. These diverse architectures create decentralized systems, inconsistent data flows, and disjointed tools, leading to blind spots that hinder the ability to detect, respond to, and prevent breaches.

Critical infrastructure sectors such as healthcare, energy, banking, and transportation will remain at heightened risk, as attackers grow more sophisticated, bypassing “know your customer” (KYC) measures, using AI-powered deepfakes for identity theft, and exploiting misconfigurations, insufficient monitoring, and weak identity management. In response, regulators are stepping up, with initiatives like the EU’s NIS2 Directive and Digital Operational Resilience Act (DORA) underscoring the urgency of robust cloud defenses.

 

The Defense Side: Cloud Security Operations

On the defense side:

  • Zero Trust architecture is fast becoming the standard, incorporating multifactor authentication (MFA), just-in-time (JIT) identity, and more granular access management (IAM) policies.
  • Cloud security operations continue to mature, leveraging AI to automate response processes and prioritize alerts.
  • Attack path prediction and analysis are increasingly critical for combating multi-step kill chains in the cloud. This evolution drives a growing demand for consistent policy enforcement across diverse environments at the networking layer, including segmentation, egress security, encryption, and anomaly detection.

 

These advancements are essential to helping organizations adapt to evolving threats while maintaining visibility and resilience.
