Salesforce Flows have transformed how organizations build on the platform. Tasks that once required custom Apex code are automated with drag-and-drop components, enabling admins, consultants, and business users to create sophisticated workflows in hours instead of days.
But there’s a downside many organizations overlook. As Flows replace custom code, they’ve also become part of your application’s attack surface.
While most security teams focus heavily on reviewing Apex code, they often give far less attention to the low-code automation running throughout the organization. That leaves security teams with a growing blind spot – one that attackers don’t ignore.
Flows Deserve the Same Security Attention as Code
It’s easy to think of Flows as “just automation.”
In reality, every Flow can:
- Read and update sensitive records
- Trigger Apex classes
- Call external systems
- Grant access to data users may not normally see
A Flow with the wrong configuration can expose customer information, bypass sharing rules, overwrite records incorrectly, or create opportunities for privilege escalation.
The fact that it wasn’t written in Apex doesn’t make it any less powerful – or any less risky.
Common Security Mistakes
Many Flow security issues aren’t caused by malicious intent. They’re usually introduced because builders are focused on solving business problems quickly.
Some of the most common risks?
Running Flows in the Wrong Context
Flows can execute in system context, allowing them to bypass object and field-level security. While this behavior is sometimes necessary, using it without careful consideration can unintentionally expose data that users shouldn’t be able to access.
Guest User Access
Experience Cloud sites often rely on guest users.If guest users can trigger Flows that access sensitive records or perform privileged actions, organizations may inadvertently expose data or create unauthorized entry points into their Salesforce environment.
Insecure Record Retrieval
Using Get Records without appropriate filters or security validation can retrieve significantly more information than intended. The result may be unnecessary access to confidential customer or business data.
Missing Fault Paths
Errors happen. Without fault handling, Flow failures may silently interrupt critical business processes, leaving administrators unaware until users begin reporting issues.
Proper error handling improves both security and operational resilience.
DML and SOQL Inside Loops
Though commonly viewed as a performance concern, inefficient Flow design can quickly lead to governor limit exceptions, failed automations, and inconsistent processes. These issues become increasingly common as organizations scale.
Traditional Code Scanners Miss Flow Risks
Most security testing tools were designed around source code. They scan Apex classes, Java, JavaScript, or other programming languages – but Flows are stored as Salesforce metadata rather than traditional code.
As a result, scanners either ignore Flows entirely or perform only basic configuration checks that miss security-specific issues. This creates a false sense of security.
An organization may successfully scan thousands of Apex files while leaving hundreds of Flows completely unreviewed.
Your Security Should Cover Everything Built on Salesforce
Today’s Salesforce applications rarely consist of code alone.
Modern implementations combine:
- Apex
- Lightning Web Components
- Visualforce
- Flows
- Metadata
- Permission Sets
- Connected Apps
- Platform configuration
If security only analyzes a few pieces of that ecosystem, vulnerabilities still slip into production through the others. Comprehensive Salesforce security requires visibility across everything that makes up the application- not just what developers write.
Bringing Comprehensive Security to Salesforce Flows
To help organizations address this growing challenge, DigitSec has expanded its Salesforce-native security platform with dedicated Flow Security Coverage.
The new rules automatically analyze Salesforce Flows to identify vulnerabilities and insecure design patterns before deployment. Covering:
Critical risks
- Guest-user accessible Flows
- System-context data exposure
- Unauthorized data access through insecure Get Records operations
High-severity findings
- Unsafe execution context
- Missing fault handling
- DML inside loops
- Apex injection risks
- Other insecure Flow patterns
Medium-severity findings
- Governor limit violations
- Inefficient SOQL and DML usage
- Duplicate operations
- Excessive data retrieval affecting performance and reliability
By analyzing Flows alongside Apex, metadata, permissions, and Salesforce configuration, organizations gain a more complete understanding of their application’s security posture.
Low-Code Doesn’t Mean Low Risk
The rise of low-code development has made Salesforce more powerful than ever. It has also changed where security vulnerabilities can originate.
Whether automation is built with clicks or code, it deserves the same level of security review before reaching production. As organizations continue to expand their use of Salesforce Flows, ensuring those automations are secure should be a standard part of every development and release process.
Because the safest Salesforce applications aren’t built quickly. They’re built securely from the start.
