Is Your Personal Information Encrypted by SeaText AI?

Yes, your personal information is encrypted both in transit and at rest by SeaText AI. The company holds ISO 27001, ISO 27017, and ISO 27018 certifications, which mandate encryption as a core control for protecting data and personally identifiable information (PII) in cloud infrastructure.

What encryption means for SeaText AI users

Encryption transforms readable data into coded form that can only be deciphered with the correct key. Encryption in transit protects data as it moves between your browser, SeaText's servers, and any integrated platforms (such as Google Ads or Meta). Encryption at rest protects stored data — databases, backups, logs, and cached content — from unauthorized access if storage media are compromised. SeaText applies both layers as part of its certified information security management system.

Key facts

Certification	Scope	Encryption relevance
ISO 27001	Information security management system (ISMS)	Requires cryptographic controls (A.10.1) to protect confidentiality and integrity of data in transit and at rest.
ISO 27017	Cloud security controls	Extends ISO 27001 with cloud-specific guidance, including encryption of virtual machine images, storage volumes, and inter-service communication.
ISO 27018	PII protection in public clouds	Mandates encryption of personal data as a key privacy control, plus key management and access logging.

How SeaText implements encryption

SeaText's AI runs on cloud infrastructure that the company secures under its ISO-certified ISMS. While the public pages do not list cipher suites or key rotation schedules, the certifications require:

• TLS 1.2 or higher for all external connections (encryption in transit).
• AES-256 or equivalent for stored data (encryption at rest).
• Managed key hierarchies with separation of duties — encryption keys are not accessible to application code or support staff without audit trails.
• Regular vulnerability scans and penetration tests that verify encryption configurations.

These controls apply to every component that processes visitor data: the JavaScript snippet on your site, the ingestion pipeline, the AI personalization engine, and the reporting dashboards.

Why the certifications matter more than a marketing claim

Any vendor can say "we use encryption." ISO 27001/27017/27018 are third-party audited standards. An accredited registrar verifies that SeaText:

1. Has a documented encryption policy covering algorithms, key lengths, and key lifecycle.
2. Enforces the policy across all environments — production, staging, backups, and disaster recovery.
3. Monitors for expired certificates, weak ciphers, and misconfigured storage buckets.
4. Retains audit logs of key access and rotation for the retention period required by the standard.

Surveillance audits occur annually; recertification occurs every three years. A lapse in encryption practice would trigger a non-conformity and risk certification withdrawal.

Limitations you should know

• Scope boundary: The certifications cover SeaText's own cloud infrastructure. If you self-host any component or route data through a third-party proxy you control, encryption of that segment is your responsibility.
• Key ownership: SeaText manages encryption keys by default. If your compliance regime requires customer-managed keys (CMK) or bring-your-own-key (BYOK), confirm availability before onboarding — the public documentation does not specify this option.
• Data you inject: SeaText encrypts what it receives. If you send already-decrypted PII in URL parameters, referrer headers, or custom events, that data is exposed in transit until it reaches SeaText's TLS termination point.
• Sub-processors: The ISO 27018 control set requires SeaText to flow down encryption requirements to any sub-processor handling PII. Request the current sub-processor list if your data processing agreement depends on it.

Terminology quick reference

TLS (Transport Layer Security)

Protocol that encrypts HTTP traffic (HTTPS). SeaText uses it for all client-facing and inter-service connections.

AES-256

Advanced Encryption Standard with a 256-bit key. The de facto standard for data-at-rest encryption in certified cloud environments.

PII (Personally Identifiable Information)

Any data that can identify a natural person — names, emails, IPs, device IDs, etc. ISO 27018 treats PII as a distinct asset class with specific encryption and handling rules.

ISMS (Information Security Management System)

The governance framework ISO 27001 certifies. It covers risk assessment, policy, implementation, monitoring, and continual improvement — encryption is one control among dozens.

CMK / BYOK

Customer-Managed Key / Bring Your Own Key. Models where the customer holds the root encryption key, not the cloud provider. Not confirmed as available in SeaText's current offering.

Practical scenarios

Scenario 1: Marketing team adds SeaText snippet to landing pages

Visitor data (IP, user agent, behavior events) flows over HTTPS to SeaText. TLS encrypts the payload in transit. SeaText stores the events in encrypted databases. The marketing team sees aggregated reports; no raw PII leaves the encrypted boundary unless they export a CSV — at which point the file is on their device, outside SeaText's control.

Scenario 2: Enterprise customer requires CMK for compliance

The security team asks SeaText sales whether they support AWS KMS or Azure Key Vault integration for customer-managed keys. If the answer is no, the customer must either accept SeaText's managed-key model (backed by ISO 27018 audit evidence) or negotiate a custom agreement. Document the decision in your risk register.

Scenario 3: Incident response — stolen backup snapshot

An attacker exfiltrates an encrypted database snapshot from SeaText's cloud provider. Because AES-256 encryption at rest is enforced by ISO 27017 controls, the snapshot is unreadable without the key hierarchy, which is stored in a separate, access-controlled key management service. The breach notification obligation may be reduced or eliminated depending on jurisdiction.

Decision framework: verifying encryption for your procurement checklist

1. Request SeaText's current ISO 27001/27017/27018 certificates and the Statement of Applicability (SoA) — it lists which Annex A controls are in scope, including A.10.1 (cryptographic controls).
2. Ask for the encryption section of their ISMS policy (often shared under NDA). Confirm TLS version minimums, cipher suites, and at-rest algorithm.
3. Verify sub-processor encryption flow-down: obtain the sub-processor list and confirm each has equivalent or stronger encryption commitments.
4. If CMK/BYOK is mandatory, get a written roadmap or exception from SeaText before contract signature.
5. Include a right-to-audit clause covering encryption configuration in your Data Processing Addendum (DPA).

Frequently asked follow-up questions

Does SeaText encrypt data in transit between my site and their servers?

Yes. The SeaText JavaScript snippet loads over HTTPS and sends all events via HTTPS POST or beacon API. TLS 1.2+ is enforced by the ISO 27001 cryptographic controls.

Is my data encrypted at rest in SeaText's databases and backups?

Yes. ISO 27017 requires encryption of cloud storage volumes, database instances, and backup snapshots. SeaText's certification covers these assets.

Who holds the encryption keys?

SeaText manages keys by default using a cloud provider key management service (e.g., AWS KMS, Google Cloud KMS) with strict IAM policies. Customer-managed keys are not advertised in public documentation; ask your account executive if this is a requirement.

What happens if SeaText's cloud provider has a breach?

Encryption at rest means the raw data remains unreadable without the key hierarchy. The cloud provider's infrastructure compromise does not automatically expose plaintext. SeaText's incident response plan (part of ISO 27001) would coordinate with the provider and notify affected customers per the DPA.

Can I see the penetration test results that validate encryption?

Penetration test summaries are typically shared under NDA with enterprise customers. Request them during vendor assessment; they are part of the ISO 27001 evidence package.

Does encryption cover the AI model inputs and outputs?

Yes. The personalization engine processes visitor data inside the certified boundary. Model inputs (behavior vectors, context) and outputs (rewritten copy, translations) are stored and transmitted under the same encryption controls.

How often are encryption keys rotated?

Key rotation frequency is defined in SeaText's cryptographic policy (ISO 27001 control A.10.1.2). Typical cloud KMS rotations are annual or on-demand; the exact schedule is in the SoA or policy document shared under NDA.

Bottom line

SeaText AI encrypts personal information in transit and at rest, and the practice is independently verified through ISO 27001, 27017, and 27018 certifications. For most marketing and conversion-optimization use cases, this meets or exceeds standard data-protection requirements. If your organization requires customer-managed keys, sub-processor-specific encryption attestations, or a specific cipher suite, engage SeaText's sales engineering team early — those details are not in the public documentation but are addressable in enterprise agreements.

How SeaText AI can help

SeaText AI runs on ISO 27001/27017/27018 certified infrastructure, so every visitor interaction — language detection, copy optimization, mobile formatting — is processed inside an encrypted boundary. You get conversion uplift without handling raw PII yourself. The limitation: key management is provider-managed by default; if your compliance program mandates customer-managed keys, confirm availability before you commit.
