01 — Security Overview

Enterprise security built for construction.

PaprTrail is designed to protect the information that matters most—contracts, project communications, schedules, notices, financial records, and legal documentation. Every customer environment is isolated, every action is authenticated, and every interaction is protected using multiple layers of enterprise-grade security.

Our commitment

  • Your data belongs to you
  • Your data is never sold or shared
  • Customer data is never used to train AI models
  • Security is built into every layer of the platform
02

02 — Data Isolation

Every customer environment is isolated.

PaprTrail uses a multi-layered security model to ensure organizations can access only their own information. Isolation is enforced through server-side authorization on every request, preventing data from crossing organizational or project boundaries.

Key protections

  • Organization and project-level data isolation
  • Server-side access controls on every request
  • Secure server-side authorization for privileged operations
  • Multiple layers of validation beyond the application interface
03

03 — AI Privacy & Security

AI that works for you—not on your data.

PaprTrail uses AI to analyze project information, generate documentation, and identify contractual risk. Every AI request is securely processed using only the information required for the specific task. Customer content remains private and is never used to train foundation models. Your proprietary contract timeline terms are never sent to the AI at all — the model only classifies an event and names which clause applies, while the actual deadline is computed on our servers from the values you configure.

AI safeguards

  • AI requests processed through secure server-side infrastructure
  • Proprietary contract deadline values never leave PaprTrail — deadlines are computed server-side, not by the AI
  • Processed through commercial AI APIs under terms that prohibit training on your data
  • Minimum necessary project context shared for each task
  • AI activity recorded within the platform audit trail

04 — Authentication & Access

Secure authentication from sign-in to sign-out.

Every authenticated session is protected using modern authentication standards, encrypted communication, and secure session management designed to minimize unauthorized access.

Authentication controls

  • Industry-standard password protection
  • Secure encrypted session management
  • Automatic session expiration and renewal
  • Server-side authorization on every protected request
05

05 — Role-Based Access

Least-privilege access by design.

Every user receives only the permissions necessary for their responsibilities. Permissions are assigned at the project level, allowing organizations to control access across teams, subcontractors, consultants, and owners.

Examples include

  • Owners and Executives
  • Project Management Teams
  • Field Operations
  • Estimating and Scheduling
  • Accounting and Finance
  • Legal and Risk Management
  • Document Control
  • Subcontractors and Read-Only Viewers
06

06 — Encryption

Protected in transit and at rest.

Data is encrypted throughout its lifecycle using modern industry standards. Whether information is being transmitted, stored, or backed up, encryption helps protect against unauthorized access.

Security measures

  • Encrypted HTTPS connections
  • Encryption for stored project data and documents
  • Secure storage for uploaded files and attachments
  • Payment information processed exclusively by PCI-compliant providers
07

07 — Audit & Accountability

Every action is recorded.

PaprTrail maintains a comprehensive audit history that provides accountability across project activities, document updates, AI interactions, and formal notices. This creates a reliable historical record for project teams, executives, and legal counsel.

Audit capabilities

  • User activity tracking
  • Document and record change history
  • Notice generation and delivery records
  • AI interaction logging for compliance and review
08

08 — Email Security

Trusted project communications.

Project emails are securely processed and routed only to authorized project environments. Incoming messages are validated before being incorporated into project records, helping preserve communication integrity.

Protections include

  • Verification of inbound communications
  • Secure routing to authorized projects
  • Preservation of message history and metadata
  • Protection against unauthorized email injection
09

09 — Infrastructure

Built on trusted cloud platforms.

PaprTrail is hosted on enterprise cloud infrastructure operated by industry-leading providers with mature security programs, continuous monitoring, and managed operational controls.

Infrastructure highlights

  • Managed cloud infrastructure with enterprise security practices
  • Continuous monitoring and automated updates
  • High availability and resilient architecture
  • No customer-managed servers or infrastructure required
10

10 — Compliance & Enterprise Support

Documentation for security and legal review.

Enterprise customers receive the documentation needed to support procurement, IT security reviews, and legal compliance requirements. Available upon request for qualifying customers.

Enterprise documentation

  • Security architecture overview
  • Data Processing Agreement (DPA)
  • Privacy and data handling documentation
  • Security review materials for vendor assessments
