Security

Security is built in, not bolted on.

Nesto handles deeply personal information—your dreams, your finances, your family's future. Protecting it is not a feature; it is the foundation of our relationship with you.

Security by Design

Security is woven into how Nesto is built, not added later. Every feature is designed with data protection in mind from the start.

Zero Trust

We never trust requests by default. Identity and authorization are verified at every access point, inside and outside our network.

Data Protection

Your data is protected with encryption in transit and at rest, strict access controls, and continuous monitoring.

Authentication & Authorization

Access is controlled through strong authentication and least-privilege authorization. You control your account and your data.

Encryption

Data is encrypted when it moves across the internet and when it is stored. We protect your information wherever it lives.

Secure Development

Our engineering team follows secure development practices—code review, dependency scanning, and automated testing.

Our security philosophy

At Nesto, we believe security is not something you add to a product—it is part of how the product is built. Our engineering teams follow a security-first development constitution that applies from the first line of code to every deployment after.

We protect the confidentiality, integrity, and availability of your data through a layered approach:

  • Confidentiality: Only the people and systems that need your data can access it, and only as far as they are authorized.
  • Integrity: Your data stays accurate and uncorrupted, protected from unauthorized modification.
  • Availability: The Service remains reliable and recoverable, with backups and monitoring.

How we protect your data

We implement multiple layers of protection throughout the platform:

  • Tenant isolation: Every user's data is logically isolated so that your information is only reachable by you and authorized systems.
  • Monitoring: We continuously monitor the Service for suspicious activity and potential threats.
  • Auditability: Security-relevant actions are logged and reviewable, supporting accountability.
  • Dependency security: Third-party libraries and services are scanned and reviewed for known vulnerabilities.
  • Backup and recovery: We maintain backups to recover data and restore service in the event of an incident.
  • Secure deployment: Releases follow a controlled, reviewable process from build to production.
  • Incident response: If an issue is discovered, we have a process to assess, contain, and resolve it promptly.

AI security

Nesto uses AI to provide personalized guidance. Our AI systems are designed with security and privacy in mind:

  • AI processing is subject to the same access controls as the rest of the platform.
  • Your conversations serve you—they are not used to train general models without your consent.
  • AI recommendations are explainable and auditable.

Responsible disclosure

We welcome reports from security researchers who identify potential vulnerabilities in Nesto. We take each report seriously and respond with appreciation, not hostility.

If you believe you have discovered a security issue, please report it privately to:

[SECURITY CONTACT EMAIL TO BE CONFIRMED]

Please do not submit vulnerability details through the public feedback form, and do not publicly disclose a vulnerability before we have had a reasonable opportunity to assess and address it.

We aim to describe our security practices accurately and conservatively. Security requires continuous vigilance, and we are committed to that vigilance every day.
