Enterprise Security Standards

Industrial facilities operate in high-consequence environments where downtime directly impacts power grids, manufacturing supply chains, and worker safety. Wrysto approaches cloud security through a strict Zero-Trust architecture and multi-layered defense-in-depth model.

No user, device, or network service is implicitly trusted, regardless of whether requests originate from a corporate plant LAN, technician 4G tablet, or external ERP integration endpoint. Every API request is verified with short-lived cryptographically signed tokens and contextual authorization.

Wrysto core production systems are hosted across Tier-3 and Tier-4 enterprise cloud facilities (AWS / Google Cloud Platform) offering premier physical, perimeter, and environmental safeguards:

All plant asset registers, work permits, technician shift handovers, and uploaded engineering schematics are safeguarded through cryptographic standards:

• Data in Transit: Enforced through TLS 1.3 (with fallback only to TLS 1.2 with secure ephemeral Diffie-Hellman cipher suites). We maintain an A+ rating on Qualys SSL Labs, strictly enforcing HTTP Strict Transport Security (HSTS) with preloading.
• Data at Rest: All relational databases, document caches, and file storage buckets are encrypted using AES-256 (Advanced Encryption Standard). Database snapshots and cold archive tapes utilize distinct rotating keys managed via Hardware Security Modules (HSM).
• Cryptographic Key Management: Keys are managed through automated Key Management Services (KMS) featuring annual automatic rotation and separation of duties between software developers and operational key custodians.

Industrial teams require fine-grained separation between mechanical technicians on the floor, electrical safety supervisors, warehouse storekeepers, and plant general managers:

• Enterprise Single Sign-On (SSO): Native integration with SAML 2.0 and OpenID Connect (OIDC) identity providers, including Microsoft Azure AD / Entra ID, Okta, Ping Identity, and Google Workspace.
• Mandatory Multi-Factor Authentication (MFA): Support for TOTP authenticators and FIDO2 / WebAuthn hardware security keys (YubiKeys) for all administrative and supervisor roles.
• Granular Role-Based Access Control (RBAC): Custom permissions controlling who can author work orders, approve purchase requisitions, release Lockout / Tagout permits, or export financial cost reports.
• Automated Session Invalidation: Inactive sessions automatically expire after configured plant idle intervals; administrative tokens can be globally revoked in one click.

Technicians frequently operate inside boiler houses, turbine halls, electrical switchgear rooms, or underground pump pits with zero cellular or Wi-Fi reception. Wrysto’s mobile offline client guarantees security while detached from the network:

• Encrypted On-Device Storage: Local inspection forms, QR asset tags, and offline work queues are stored in encrypted client-side storage (SQLCipher / AES-encrypted IndexedDB) protected by device-level sandboxing.
• Biometric Device Unlock: FaceID and fingerprint biometric authentication prevent unauthorized access to open checklists if a handheld device is left on a plant workbench.
• Tamper-Resistant Sync Queues: Offline actions are cryptographically signed with technician session keys and sequenced with monotonic timestamps to prevent replay attacks or queue tampering during synchronization.
• Remote Wipe & Device Revocation: Lost or stolen technician tablets can be immediately wiped of all cached drawings and plant registers from the central admin dashboard.

Security is engineered into our product from architectural inception through production deployment:

• Automated SAST & DAST Scanning: Every pull request undergoes Static Application Security Testing (SAST) and software composition analysis (SCA) to detect vulnerabilities in third-party libraries.
• OWASP Top 10 Mitigation: Built-in safeguards against injection (SQLi, NoSQLi), Broken Object Level Authorization (BOLA), cross-site scripting (XSS), and CSRF token manipulation.
• Peer Code Review: All production code requires mandatory peer review and approval by designated security engineering leads.
• Immutable CI/CD Deployments: Production deployments are fully automated via secure CI/CD pipelines with cryptographic artifact signing; direct SSH production access is strictly restricted.

We continuously test our defenses against the latest adversarial tactics:

• Annual Third-Party Penetration Testing: Independent, accredited CREST-certified cybersecurity auditing firms perform comprehensive black-box and white-box penetration tests on our web APIs, mobile apps, and cloud networks.
• Automated Vulnerability Scanning: Daily infrastructure vulnerability scans scan container images, OS packages, and network ports for zero-day CVE disclosures.
• Critical Patching SLA: Critical security vulnerabilities (CVSS 9.0+) are mitigated within 24 to 48 hours; High severity vulnerabilities are patched within 7 calendar days.

Industrial facilities rely on Wrysto for continuous daily shift handovers and scheduled emergency maintenance. Our disaster recovery framework is architected for extreme resilience:

*All backup images are encrypted with dedicated keys and tested through simulated failover drills conducted quarterly.

In the event of an industrial incident, insurance underwriters and national safety boards demand forensic verification of maintenance history and safety clearance:

Cloud security is a collaborative partnership between Wrysto and the industrial enterprise:

Wrysto maintains a 24/7/365 Computer Security Incident Response Team (CSIRT) governed by NIST SP 800-61 guidelines. In the confirmed event of an unauthorized security breach affecting Customer Plant Data:

• Prompt Customer Notification: Wrysto will formally notify Customer designated security officers via email and telephone within 48 hours of verified confirmation.
• Comprehensive Containment: The CSIRT will immediately isolate compromised instances, revoke affected credentials, and apply countermeasures to contain the incident.
• Forensic Post-Mortem: Within 14 calendar days, Wrysto will provide an exhaustive written root-cause analysis (RCA), timeline of events, affected scope, and permanent corrective engineering mitigations.

We actively collaborate with cybersecurity researchers and customers who practice ethical, responsible vulnerability disclosure. If you discover a suspected vulnerability or security concern in any Wrysto application or service:
