It turns out that “April showers” aren’t reserved solely for the weather. In the news this month, we saw new data highlight growing cloud network security challenges, unnerving cyber threat trends gain strength, and concern voiced by enterprises on the front lines.
Together, these developments signal that – whether you’re managing edge devices, cloud firewalls, or SaaS integrations – network security as it exists today requires immediate defensive recalibration with cloud native solutions at the forefront.

CNCF survey reveals widespread Kubernetes adoption, growing reliance on cloud-native technologies
A new survey from the CNCF reveals 80% of IT professionals have already deployed Kubernetes in production with an additional 13% testing it – showing near-universal adoption alongside dramatic growth in container usage. If you’re a network security professional, note the even split between on-premises and public cloud deployments, suggesting complex hybrid environments requiring unified security strategies. Also note the significant increase in CI/CD platform adoption (up 30% year-over-year to 60%), which points to expanding attack surfaces and security integration challenges. Although 57% of respondents are now using automated vulnerability detection tools, cultural resistance (46%) and skills gaps (38%) remain as top challenges.

CyberRatings: Cloud Firewalls Have Gaping Holes
Independent testing firm CyberRatings.org’s Q1 2025 report revealed that cloud-based firewalls hosted on major public clouds are performing poorly when put to the test – with some receiving 0% effectiveness scores. The discrepancy stems from versioning differences between third-party solutions and their cloud-hosted counterparts. As CyberRatings noted, cloud firewalls frequently failed basic security tests like blocking exploits and evasions. Based on these findings, CyberRatings explicitly advised customers to avoid using native cloud service provider firewalls and instead rely on third-party security solutions for cloud environments.

Verizon DBIR Flags Major Patch Delays on VPNs, Edge Appliances
Verizon issued its popular 2025 Data Breach Investigations Report (DBIR), revealing an 8x yearly increase in edge-targeted attacks – which now constitute 22% of all exploitation attempts. Once compromised, these edge devices provide attackers with network footholds enabling lateral movement, data exfiltration, and ransomware deployment—a vulnerability exacerbated by concerning statistics like 32-day median patch delays and 46% of vulnerabilities remaining unpatched after a full year. The report highlights how conventional zero trust implementations often stop at identity and endpoint controls while neglecting network security, leaving critical gaps in protection. With edge infrastructure components like VPNs and firewalls transforming from defensive assets into primary attack vectors, embedding zero trust principles directly into the network data plane is more important than ever before.

Medusa Ransomware Claims NASCAR Breach in Latest Attack
Following on the heels of last month’s warnings from CISA and other security groups about the new Medusa ransomware, we started April with news that the groups had hit NASCAR – demanding $4M ransom and leaking internal files. The group also claimed responsibility for hacks of Bridgebank, McFarland, Pulse Urgent Care, and more. Cloud migration has created a perfect storm for next-generation ransomware, which now expertly navigates the architectural weaknesses between disconnected cloud services, slipping through segmentation cracks, exploiting permission blind spots, and leveraging unrestricted outbound connections. The battleground has shifted skyward – ransomware no longer merely infiltrates your servers, it has ascended to your cloud. This isn’t tomorrow’s threat; it’s today’s reality demanding immediate defensive recalibration.

JPMorgan Chase’s call to stay skeptical on the cloud and AI should resonate with everyone
Squeaking in at the end of the month, JPMorgan Chase’s CISO wrote an open letter that’s gained wide circulation. In it, he warned that hackers are increasingly targeting SaaS vendors as strategic entry points to breach multiple organizations. This reality demands that the SaaS model embrace shared responsibility for security with transparent, bidirectional partnerships. Rather than retreating from digital interconnectedness, organizations must integrate security tools directly into development lifecycles while both vendors and customers maintain vigilance through continuous monitoring and proactive vulnerability management. Enterprises, it’s time to brush up on practical steps you can take to reprioritize security, modernize your security architecture, and collaborate to close vulnerabilities caused by insecure integrations.
If you’re in cloud, networking, and security, your plate is already full with keeping your organizations’ infrastructure running effectively. However, in today’s technology climate, which is changing at the pace of AI, staying informed is not just an advantage — it’s a necessity.
Our monthly cloud network security must-reads are curated to deliver critical insights, emerging trends, and pivotal developments that every cloud, networking, and security professional needs to know. By distilling the month’s most significant stories into a concise, digestible format, we aim to empower technology leaders and practitioners with the knowledge that can transform potential challenges and vulnerabilities into strategic opportunities.
Whether you’re a chief information security officer, network architect, cloud engineer, or security analyst, these insights will help you stay ahead of emerging risks, optimize your infrastructure, and make more informed technological decisions that protect and propel your organization forward.
