Top Security Concerns for DevOps in 2026: Expert Insights and Predictions

Development Environments Under Attack

In 2025, trusted development environments became a haven for cyber attackers. Artificial intelligence-integrated development platforms expanded the attack surface, leading to a surge in malicious activity.

Key Takeaways from the Report

Rethink AI Assistants

Artificial intelligence can be a valuable asset for developers, but its integration into development platforms increases the risk of malicious activity. In 2025, researchers identified 68 AI-related incidents across popular development platforms. To mitigate these risks, organizations should adopt a zero-trust approach to AI assistants by implementing strict input data sanitization, human verification, and least-privilege access controls.

Be Wary of Public Repositories

Supply chain attacks are becoming increasingly common due to their scalability. Threat actors inject malicious code into open-source repositories, which then propagate into private corporate repositories through misconfigured Continuous Integration/Continuous Deployment (CI/CD) pipelines or long-lived tokens. Organizations must verify dependencies, third-party code, proof-of-concepts, and tools, and secure CI/CD pipelines and developer workflows through short-lived, least-privilege tokens and continuous monitoring.

Prioritize Identity Hygiene

Secret leaks are a significant concern, as they often go unnoticed until they become major incidents affecting numerous repositories. In 2025, researchers observed a steady increase in credential theft. To prevent this, organizations must prioritize identity hygiene, using frequently rotated credentials and short-lived tokens with least-privilege access. They should also monitor CI/CD workflows, repositories, dependencies, and cloud accounts, adopt phishing-resistant Multi-Factor Authentication (MFA), and practice careful secret management.

Address Configuration and Automation Errors

Configuration and automation errors were the primary cause of development environment outages in 2025, even among well-established cloud providers. These failures can scale globally downstream, resulting in financial, legal, operational, and compliance issues. To mitigate this risk, organizations can employ a multi-cloud or hybrid strategy, enabling easy migration between providers or running their code entirely on-premises.

Stay Vigilant Against Vulnerabilities

More than half of all patched vulnerabilities in 2025 were classified as critical or high-severity. Organizations must stay informed about vulnerability bulletins from development platforms and promptly apply patches. Additionally, they should conduct regular third-party dependency audits and anomaly monitoring.

Harden Against Phishing Attacks

Phishing attacks continue to evolve, using trusted identity flows, cloud services, and OAuth to bypass Multi-Factor Authentication (MFA). Organizations can resist these attacks by implementing granular Conditional Access policies and hardening OAuth flows, consent approvals, and authorized applications. Behavior-based detection is also essential.

Establish Clear Data Handling Rules

While cloud providers are considered secure, organizations remain accountable for protecting sensitive or personal information stored in the cloud. To ensure compliance with regulations like GDPR or HIPAA, organizations must establish clear data handling rules with their cloud provider, prioritize vulnerability management, rapid incident response, and continuous monitoring.

According to the report, organizations can better defend themselves against sophisticated threats in the development environment by grasping these seven hard truths.
