Legal document automation delivers enormous efficiency gains—but it also introduces serious security responsibilities. When you run Docassemble in a U.S. law firm or legal aid organization, you’re not just hosting a web application. You’re safeguarding confidential client data, privileged communications, and court-ready legal documents.
This is why docassemble security best practices aren’t optional. They’re foundational.
This guide provides a practical, real-world security checklist for organizations using Docassemble—covering infrastructure, application security, access control, data protection, and operational safeguards.
Why Security Matters More in Legal Automation
Legal organizations handle some of the most sensitive data possible:
- Personally identifiable information (PII)
- Financial records
- Immigration status
- Medical and family law details
- Attorney-client privileged content
A single misconfiguration can expose thousands of interviews and documents. That’s why document automation security must be treated as a first-class concern—not an afterthought.
Docassemble is powerful and flexible, but like all open-source platforms, security depends on how it’s deployed and managed.
1. Secure Your Hosting Environment First
Your security posture starts below Docassemble—at the infrastructure level.
Checklist:
- Use a reputable cloud provider (AWS, Azure, GCP)
- Isolate Docassemble in a private VPC or subnet
- Restrict SSH access via IP allowlists
- Disable password-based SSH (use key-only access)
- Apply OS security patches regularly
This aligns with best practices for open source legal tech security, where infrastructure missteps are the most common attack vector.
2. Enforce HTTPS Everywhere (No Exceptions)
All Docassemble traffic must be encrypted in transit.
Checklist:
- Enforce HTTPS using TLS 1.2+
- Use certificates from a trusted CA (Let’s Encrypt or enterprise CA)
- Redirect all HTTP traffic to HTTPS
- Disable weak ciphers and protocols
Without this, user answers—including SSNs and financial data—can be intercepted.
3. Lock Down Admin and Developer Access
Docassemble’s admin interface is powerful—and dangerous if exposed.
Checklist:
- Never expose admin endpoints publicly
- Restrict admin access by IP
- Use strong, unique passwords
- Enable multi-factor authentication where possible
- Separate admin, developer, and content editor roles
Strong role separation is a core element of docassemble security and is often overlooked in early deployments.
4. Apply Flask Application Security Best Practices
Under the hood, Docassemble is a Python/Flask application. That means it inherits both Flask’s flexibility and its risks.
Your flask application security checklist should include:
- CSRF protection enabled
- Secure session cookies
- Strict input validation
- Protection against XSS and injection attacks
- Safe file upload handling
These steps align with broader python web app security best practices, which are essential in legal environments.
5. Protect Interview Data and Generated Documents
Docassemble stores:
- User answers
- Uploaded files
- Generated PDFs, DOCX, and RTF files
Checklist:
- Encrypt data at rest
- Restrict database access to application services only
- Separate storage for sensitive documents
- Define retention policies (especially for legal aid orgs)
- Secure backups with encryption and access controls
Good document automation security means knowing exactly where sensitive data lives—and who can access it.
6. Harden Authentication and User Sessions
Public-facing legal interviews attract abuse attempts.
Checklist:
- Use short-lived sessions
- Rotate session keys regularly
- Prevent session fixation
- Invalidate sessions on logout
- Rate-limit login and interview endpoints
These controls reduce the risk of automated attacks, credential stuffing, and session hijacking.
7. Secure File Uploads and Attachments
Many Docassemble workflows allow users to upload documents.
Checklist:
- Limit allowed file types
- Enforce file size limits
- Scan uploads for malware
- Store uploads outside the web root
- Rename files server-side
File handling is one of the most common vulnerabilities in legal automation systems.
8. Log Everything (But Log Safely)
Logging is critical for incident response—but logs can become a liability if mishandled.
Checklist:
- Log access attempts, errors, and admin actions
- Never log sensitive answers or documents
- Protect logs from unauthorized access
- Retain logs according to policy
- Monitor logs for anomalies
This balance is essential for open source legal tech security in regulated environments.
9. Secure Integrations and External Services
Docassemble often integrates with:
- Payment gateways
- Identity verification services
- Court e-filing systems
- Email and SMS providers
Checklist:
- Store API keys securely (never in code)
- Rotate secrets regularly
- Use least-privilege API scopes
- Validate all inbound webhooks
Third-party integrations are a growing attack surface.
10. Apply Least-Privilege Database Access
Your database should not be a shared free-for-all.
Checklist:
- Separate read/write roles
- Restrict direct database access
- Encrypt database backups
- Monitor for unusual queries
This is a core requirement in any serious docassemble security best practices program.
SESSION_COOKIE_SECURE = True
SESSION_COOKIE_HTTPONLY = True
SESSION_COOKIE_SAMESITE = 'Lax'
WTF_CSRF_ENABLED = True
PREFERRED_URL_SCHEME = 'https'
12. Prepare for Audits, Not Just Attacks
Law firms and legal aid orgs increasingly face:
- Client security questionnaires
- Grant compliance reviews
- Court IT assessments
Checklist:
- Maintain security documentation
- Record patching and update schedules
- Document access controls
- Track incident response procedures
Security that can’t be explained often fails audits—even if it works technically.
