SAST Tools: Core Features & How to Choose the Best SAST Solution

Modern engineering teams ship code faster than ever. But here’s the catch: rapid deployment means security mistakes can slip through just as quickly. That’s where SAST—Static Application Security Testing—comes in.

SAST tools analyze code before it runs, helping you catch vulnerabilities early in the development lifecycle. But with so many options on the market, how do you know which one deserves a place in your pipeline?

This guide walks you through:

• The must-have SAST capabilities every team needs
• Advanced features that separate great tools from average ones
• A practical framework for choosing the right SAST solution
• Why Aikido is one of the strongest SAST options available today

Let’s start with the essentials.

Must-Have SAST Features & Capabilities

These are the fundamentals. If a tool can’t deliver on these, it’s likely to become shelfware or slow down your developers instead of helping them. For a comprehensive background on how SAST compares to other approaches, check out our Application Security Testing Overview.

Broad language and framework support

Your SAST tool should work across your entire codebase—not just the “easy” parts. Modern engineering teams often work in polyglot environments or rely on monorepos. If the scanner doesn’t support your languages or frameworks, you’ll end up with gaps that undermine your entire AppSec program. For reference, see OWASP’s Application Security Verification Standard for baseline expectations.

Source-level (or bytecode-level) analysis without execution

SAST should analyze code without running it. That’s the whole point. Static scanning provides fast feedback, works in any environment, and eliminates the risk associated with executing untrusted or unbuilt code. For more technical details, our How SAST Works guide breaks down the process step by step.

Data-flow, control-flow, and taint analysis

Basic pattern matching isn’t enough. You need a SAST engine that understands how data moves through your application. That’s what uncovers real issues—like user input flowing straight into SQL queries, insecure deserialization across modules, or untrusted data reaching file paths. Learn more in our Deep Dive: Data Flow Analysis in SAST.

Integration with developer workflows (IDE, CI/CD, version control)

If you want developers to actually use a SAST tool, it must show up where they already work. That means inline PR comments, CI/CD gates, commit-level scanning, and IDE plugins that surface issues early. The goal is to make security a natural part of the process, not a separate chore. For best practices, read Integrating Security into CI/CD Pipelines.

Low false-positive rate and meaningful prioritization

You’ve probably heard this before: “We tried SAST, but the noise was too high.” False positives kill adoption. A strong SAST solution should be accurate, context-aware, and designed to surface what truly matters—real vulnerabilities, not stylistic opinions. You can explore industry benchmark data on NIST’s National Vulnerability Database.

Clear and actionable remediation guidance

Finding vulnerabilities is only half the job. Developers need to understand what went wrong and how to fix it. Good remediation guidance should be easy to follow, language-specific, and grounded in real-world best practices. SANS Institute offers practical remediation strategies, and our Remediation Playbook gives hands-on examples tailored for development teams.

Fast performance and scalability

Slow SAST tools bottleneck your CI/CD pipeline and frustrate engineers. As your codebase grows, your scanner should scale with it—supporting large repos, microservice architectures, and distributed teams without grinding to a halt.

Advanced SAST Features

These aren’t strictly required, but they can make a massive difference—especially as your team scales or your security posture matures. For an in-depth look at extended features, see our Advanced Code Security Features guide.

Custom rule authoring and policy enforcement

Every organization has unique patterns, frameworks, and internal conventions. A customizable rule engine lets you enforce your own security policies and catch issues specific to your codebase—not just generic vulnerabilities. Learn more about rule customization in our Policy Management section.

Inline IDE feedback and early warnings

Imagine catching an injection flaw while typing, before the commit even happens. IDE-level scanning shifts security even further left, reducing the cost and effort of fixing issues later in the process. Check out our IDE Integration for SAST article for setup tips.

Automated or AI-assisted remediation

Some advanced SAST tools now recommend fixes or even auto-generate patches. This helps reduce friction, especially for repetitive or well-understood issues. For large teams, autofix capabilities can reclaim hours of developer time.

Context-aware severity scoring

A vulnerability in a dead internal endpoint isn’t the same as one in a public API handling production data. Advanced tools incorporate environmental context to ensure critical issues rise to the top. For best practices on risk assessment, see the OWASP Risk Rating Methodology.

Multi-file / cross-module taint tracking

Real vulnerabilities rarely appear in isolation. Cross-file analysis helps the scanner understand how data flows across modules, packages, or layers of the application—surfacing deeper, more meaningful findings. For more on taint analysis, refer to this SANS white paper.

Additional scanners (SCA, secrets detection, IaC, container security)

While not part of pure SAST, having these capabilities in the same platform makes your life simpler. Instead of juggling multiple tools, teams get a unified security view across code, dependencies, infrastructure, and runtime. Our Security Platform Overview explains how these scanners complement SAST.

On-prem or private cloud deployment

For companies working with sensitive IP or strict compliance requirements, on-prem installation or private cloud scanning can be a must. It ensures code never leaves your environment. Learn about secure deployments in our Deployment Models guide, and see compliance benchmarks at the National Vulnerability Database.

Enterprise-level scalability

RBAC, audit logs, team workspaces, and policy-based controls become crucial as engineering teams grow. Advanced SAST platforms support these out of the box. Explore Enterprise SAST Management for details.

How to Choose the Best SAST Tool

Choosing a SAST tool isn’t about ticking boxes—it’s about finding the one that fits your workflow, your team, and your long-term needs. For a comprehensive overview, check our Guide to Selecting a SAST Solution. Here’s a practical way to evaluate your options:

1. Start with your languages, frameworks, and architecture

List out your tech stack. Any SAST tool that doesn’t support your primary languages or frameworks is an immediate no. And if you use monorepos or microservices, make sure the tool can handle them efficiently. For an up-to-date reference on language and framework risks, visit the OWASP Top 10.

2. Evaluate core SAST accuracy and noise level

Accuracy matters more than breadth. A tool with dozens of rules but high noise will hurt your team’s credibility and slow adoption. Look for tools known for low false positives and context-aware findings. For more tips on evaluating false positives, see our SAST Accuracy Explained and review expert discussions at SANS Security Resources.

3. Check how well it integrates into your workflow

Ask yourself:

• Will this add friction for developers?
• Does it work in IDEs and PRs?
• Will it slow our CI/CD pipeline?
  If the answer is yes to any of these, it’s a red flag. Our DevSecOps Integration Checklist covers the key steps for a smooth setup.

4. Consider your maturity and future needs

Are you solving just for SAST today, or do you want one platform for SAST, SCA, IaC scanning, secrets detection, and more? A unified platform can reduce overhead and improve visibility over time. For more on scaling application security, see OWASP’s Application Security Verification Standard.

5. Run a proof-of-concept (PoC)

Select a few representative repositories and compare:

• How many issues each tool finds
• How many are false positives
• How long scans take
• How easy remediation feels
  The PoC phase reveals more than any marketing page ever will. Our SAST PoC Playbook provides a checklist and sample evaluation metrics.

6. Consider total cost vs long-term value

A slightly more expensive tool that saves developer time, improves accuracy, and scales with your team often ends up cheaper in the long run. Evaluate cost holistically—not just licensing fees.
