01. Managed app infrastructure

Managed app infrastructure removes the complexity of maintaining secure servers and systems by providing professionally monitored hosting environments. This means your application runs on regularly updated, patched and monitored servers that meet industry security standards.

The infrastructure includes automated backup systems, disaster recovery protocols and 24/7 monitoring for suspicious activities. Professional teams handle server maintenance, security updates and threat detection, significantly reducing the risk of infrastructure-level vulnerabilities that cybercriminals often exploit.

Base44 provides fully managed infrastructure as part of its platform, automatically handling server security, updates and monitoring. This means your app benefits from enterprise-level security without requiring dedicated infrastructure management expertise or resources.

02. Custom permission controls

Permission controls determine what actions users can perform within your application and what data they can access. Implementing granular permission systems ensures users only have access to features and information necessary for their specific roles or needs.

Effective permission controls follow the principle of least privilege, where users receive the minimum permissions required to perform their tasks. This approach limits the potential damage if user accounts become compromised and prevents unauthorized access to sensitive application areas.

Base44 includes sophisticated custom SSO and permissions tools that allow you to create custom user roles and define specific access levels for different application features. The platform's permission system integrates seamlessly with user authentication, making it simple to control who can access what within your app.

Strong authentication is the first line of defense

Permission controls work best when paired with strong authentication. At minimum, enforce multi-factor authentication (MFA) for any app that handles sensitive data, so a stolen password alone isn't enough to grant access. Session management matters too: sessions should time out after a period of inactivity, tokens should be stored securely and users should be required to re-authenticate before performing sensitive actions like changing passwords or approving transactions. Biometric authentication (fingerprint or face recognition) adds a second layer that's both more secure and more convenient for users. Base44's built-in authentication system handles session management and supports custom SSO integrations, so you can enforce these controls without building them from scratch.

03. Perform security scans

Regular security scans identify vulnerabilities in your application code, dependencies and configuration before malicious actors can exploit them. These scans examine your app for known security flaws, outdated components and potential entry points for cyber attacks.

Automated scanning tools can detect various threats including SQL injection vulnerabilities, cross-site scripting flaws and insecure data storage practices. The frequency of these scans should increase during development phases and continue throughout your app's lifecycle to catch new vulnerabilities as they emerge.

Base44 incorporates automated security scanning into its development workflow, continuously monitoring applications for potential vulnerabilities. The platform provides detailed reports on security findings and offers guidance on addressing any identified issues, ensuring your app maintains strong security posture over time.

04. Secure your source code

Source code protection prevents unauthorized access to your application's underlying logic, algorithms and sensitive information embedded within the code. Exposed source code can reveal security vulnerabilities, API keys and business logic that competitors or malicious actors might exploit.

Code security involves implementing access controls for development repositories, using code obfuscation techniques and ensuring sensitive information never appears in plain text within your codebase. Regular code reviews and static analysis help identify potential security issues before they reach production environments.

Base44 provides secure development environments with built-in code protection measures. The platform handles code compilation and deployment securely, ensuring your source code remains protected while maintaining efficient development workflows for your team.

05. Security dashboard & row‑level security (RLS)

A robust app doesn’t just protect the perimeter, it controls who can see or modify each individual record. Row‑level security (RLS) lets you define granular rules for every data entity in your app so that only authorized people can read, edit or delete specific rows. In Base44’s security dashboard you’ll see a list of your data entities and whether each one is public or restricted. 

Base44 makes RLS management simple. If you're unsure where to start, Base44's built-in security check scans your app for missing RLS rules, exposed secrets or unsafe backend functions and highlights issues. You can fix them all with a single click or address each one individually and Base44 recommends running the scan before publishing your app.

By centralizing RLS management and automating security scans, Base44’s security dashboard helps you enforce least‑privilege access and maintain strong data‑level protection across your entire application.

06. Encryption

Encryption transforms sensitive data into unreadable formats that can only be decoded with the proper decryption keys. This protection ensures that even if cybercriminals intercept your data during transmission or storage, they can't access the actual information without the encryption keys.

Implement encryption for data both in transit (moving between your app and servers) and at rest (stored in databases or files). Use industry-standard encryption algorithms and ensure encryption keys are properly managed and regularly rotated to maintain security effectiveness.

Base44 automatically implements end-to-end encryption for all data transmission and storage. The platform uses advanced encryption standards and manages encryption keys securely, ensuring your app's data remains protected without requiring complex encryption implementation on your part.

"Encryption is a fundamental aspect of app security, safeguarding sensitive data both in transit and at rest. Implementing strong encryption ensures that user and business information remains protected throughout the application lifecycle." - Ilay Granot, Marketing at Base44

07. API security controls

Application Programming Interfaces (APIs) serve as connection points between your app and external services, making them potential targets for cyber attacks. Securing these connections involves implementing authentication, rate limiting and input validation to prevent unauthorized access and abuse.

API security includes using secure protocols like HTTPS, implementing proper authentication mechanisms and validating all incoming data to prevent injection attacks. Regular API security testing helps identify vulnerabilities in these critical connection points.

Base44 provides comprehensive API security features including automated threat detection, rate limiting and secure API endpoints. The platform monitors API usage patterns to identify suspicious activities and implements security measures that protect against common API-based attacks.

08. Pentesting

Penetration testing involves security experts attempting to hack your application using the same techniques malicious actors would employ. This proactive approach identifies vulnerabilities that automated scans might miss and provides insights into how real attacks might unfold.

Professional penetration testing should occur regularly, especially after significant updates or changes to your application. The results provide detailed reports on discovered vulnerabilities along with recommendations for addressing each identified security gap.

Base44’s built-in security monitoring and vulnerability detection systems complement external pentesting efforts. The platform's security features help address common vulnerabilities that penetration tests typically discover.

09. Secure data storage

Secure data storage protects sensitive information from unauthorized access, both from external threats and potential internal breaches. This involves encrypting stored data, implementing proper access controls and ensuring data backup and recovery procedures meet security standards.

Consider what data your app actually needs to store and minimize data collection to reduce potential exposure. Implement data retention policies that automatically remove outdated information and ensure compliance with privacy regulations that apply to your users.
