Their faster delivery cycles change when security decisions must be made and what must be protected: the application, its dependencies and configuration, the systems that build and deploy it, and the governance around SaaS and low-code solutions. Security works best when it is part of planning, development, release, and ongoing operations—not a review left until the end.
How do Agile and DevOps change software security risk?
In continuous delivery, design choices, code changes, dependencies, configuration, and deployments can reach production quickly. A weakness that might once have waited for a later release can now move through the delivery process on a much shorter cycle. If security review happens only at the end, teams may have less time to identify and address it before release.
The answer is not to abandon fast delivery or treat Agile as the source of a vulnerability. It is to integrate security into the lifecycle and make the engineering systems that enable delivery part of the security boundary. NIST’s Secure Software Development Framework (SSDF) Version 1.1 describes secure-development practices that can be integrated into an organization’s SDLC regardless of its lifecycle model. NIST’s September 2026 DevSecOps publication emphasizes ongoing security monitoring and improvement as development environments grow more complex and fast-moving.
What are the main security risks of DevOps?
Risks fall into three related areas: weaknesses in the application and its components, weaknesses in the delivery systems that can affect production, and governance gaps in how people and services access data and deploy changes.
#1 Best Overall
Application, dependency, and configuration risks
Rapid development can expose design weaknesses, vulnerable third-party dependencies, configuration mistakes, flaws in infrastructure automation, and poor secrets handling. Depending on the weakness, consequences can include unauthorized access to data, compromised credentials, malicious code in a build artifact, or harm that reaches downstream users through a software supply chain. Microsoft’s Shift DevOps to DevSecOps guidance identifies these as risks to address across the development lifecycle.
Pipeline and engineering-system risks
Repositories, CI/CD pipelines, deployment automation, infrastructure-as-code (IaC), developer identities, service accounts, and credentials are not merely supporting tools. They may have permission to change code, build artifacts, or deploy to production. If an attacker compromises a sufficiently privileged system or identity, they may be able to alter what gets built or released.
OWASP’s DevSecOps guidance warns that CI/CD tooling expands the attack surface. It also describes CI/CD as “an advantage for SecOps, a privileged entry point for security measures and controls.” The practical implication is that teams must govern who can change pipeline code, which identities pipelines use, what credentials each pipeline can access, and which changes require human review.
SaaS and customer-data governance risks
A customer-facing SaaS provider is responsible for protecting the data and business operations customers entrust to the service. Tenant boundaries, identity, resource access, and customer-specific compliance expectations need deliberate decisions. Microsoft’s SaaS workload guidance also highlights a trade-off: multiple tenants can increase operational overhead and create additional security risk if they are poorly managed. Tenant separation should follow a clear need, while restrictive access controls should be paired with a workable emergency-escalation process.

Low-code and citizen-development risks
Low-code and no-code tools lower barriers to building applications, but they do not remove responsibility for security or governance. OWASP’s Top 10 Risks for Citizen Development covers security and governance issues associated with software built using low-code/no-code platforms and related tools. Microsoft likewise notes that risks apply across low-code/no-code platforms and that platform features need to be combined with organizational processes.
The available guidance supports this general governance concern; it does not establish a comparative security ranking of individual low-code vendors or products. Organizations should evaluate the platform they use and the way their teams configure and govern it, rather than assuming that a low-code label makes an application safe or unsafe.
Rank #3
How do you secure a CI/CD pipeline?
Use a layered approach. Automated checks can find certain classes of problems, while identity controls, review requirements, and restricted permissions reduce the chance that a pipeline or its credentials can be misused. Choose checks for the architecture and lifecycle rather than adding every possible tool without regard to how the team works.
Build security into planning and design
- Define security requirements alongside functional requirements, including the data the application handles, the access it needs, and the risks that matter for the service.
- Consider security during design and planning, so important decisions are not deferred to a final release gate.
- Use a secure-development framework such as NIST SSDF to integrate practices into the SDLC without requiring one particular development methodology.
Add pipeline checks that fit the software
OWASP’s DevSecOps guidance identifies several checks that may be incorporated into a delivery workflow. Their value depends on the application architecture, the technologies in use, and where a check can provide useful feedback.
- Credential scanning can help detect secrets exposed in code or repositories.
- Software composition analysis (SCA) can help identify risks in third-party components and dependencies.
- Static application security testing (SAST) can examine source code for certain classes of weaknesses.
- IaC scanning can check infrastructure definitions for configuration issues before deployment.
- Supply-chain protections, including artifact provenance or signing where appropriate, can help establish how a build artifact was produced and protect the integrity of what is released.
- API security checks can address risks in the interfaces through which applications expose functionality or data.
- Dynamic testing (DAST) can test a running application for certain weaknesses.
These controls are complementary, not interchangeable guarantees. Select and place them according to the software’s design and lifecycle, and make sure results can be acted on by the people responsible for the relevant code or service.
Restrict who and what can change or deploy software
Microsoft’s CI/CD governance example uses least privilege, protected branches, passing CI checks, and peer approval for changes that can trigger deployments. Those ideas are vendor-agnostic: require appropriate review for consequential changes, protect the branches that feed releases, and limit the permissions of people and automation.
- Restrict access to repositories, pipeline definitions, deployment environments, and service connections to the identities that need it.
- Give each pipeline and service account only the permissions it needs; do not treat automation identities as harmless simply because they are not human users.
- Limit which pipelines can access secrets and credentials, and avoid granting broad access by default.
- Require CI checks and peer review for material changes that can affect production deployments.
- Make changes to pipeline code and deployment permissions subject to appropriate review, not just changes to application code.
How should a SaaS team govern customer data and access?
Start with the service’s customer, data, and operational requirements. Decide how tenants are separated, which identities and roles can access resources, what customer-specific compliance needs apply, and how the team will respond when normal access controls prevent urgent work.
- Set tenant boundaries deliberately. Choose separation that meets a clear customer, security, or operational need, and account for the overhead of managing it consistently.
- Apply least privilege. Use role-based access control (RBAC) and policy to limit access to resources. Microsoft’s SaaS guidance also identifies resource locks as a potentially useful control.
- Plan for exceptions. Strong restrictions can slow incident response or other urgent operations if no escalation path exists. Define how authorized responders can obtain necessary access and how that access is governed.
- Account for customer expectations. Consider customer-specific compliance requirements when making choices about identity, access, and service operations.
These decisions involve operational trade-offs as well as security. A control that is difficult to operate may create pressure for informal workarounds, so access restrictions and response procedures need to be designed together.

How do you govern low-code and no-code development?
Governance should make it clear who can create and deploy applications, what information and connections those applications can reach, and which solutions need additional review. The following is a practical synthesis of OWASP’s citizen-development scope and Microsoft’s emphasis on combining platform capabilities with organizational processes; it is not a vendor-specific checklist.
- Identify creators and deployment rights. Know which users or teams can create, publish, or change applications and workflows.
- Understand data and connector access. Determine what data each solution can use and which connectors or services it can reach.
- Know which controls the platform enforces. Distinguish protections built into platform features from responsibilities the organization must meet through its own processes.
- Set review expectations. Establish which applications need stronger review or professional development practices, based on their data access, purpose, and impact.
- Make oversight part of ongoing operations. Revisit access and deployment practices as applications, users, and business needs change.
How should an organization choose security controls?
There is no single tool choice established as right for every team. OWASP advises tailoring pipeline steps to the SDLC and architecture, while Microsoft’s SaaS guidance highlights the need to balance security with operational efficiency. Compare options on the questions that affect your actual service and delivery process:
- Which in-scope risks does the control cover: code, dependencies, IaC, APIs, or runtime behavior?
- How does it fit the team’s workflow, and can people address its findings without creating unproductive friction?
- What permissions, identities, and credentials does the tool or pipeline require?
- Does the process support auditability, protected branches, approvals, and artifact provenance where needed?
- Does the approach fit the organization’s SaaS responsibilities, customer or regulatory expectations, and operational needs?
Security should remain part of delivery and operations as software changes. The combination of lifecycle practices, pipeline safeguards, access governance, and continuing monitoring is more useful than treating a one-time scan or release approval as proof that a service is secure.
