AI Security at ZeroBounce

At ZeroBounce, we take a proactive and transparent approach to securing our AI systems. Our commitment is grounded in real-time monitoring, strict adherence to company-wide policies, and a rigorous validation process.

Post-Deployment Monitoring & Governance

All AI deployments are continuously monitored in real time. User inputs are retained for 30 days in accordance with our global data policy, after which they are securely deleted. Systems for appeal, override, decommissioning, incident response, and change management follow established company-wide security protocols.

Content Validation & Bias Mitigation

We ensure our AI generates accurate and responsible content by restricting input data to thoroughly vetted public sources—namely, our website and official documentation. Each AI release undergoes rigorous validation to mitigate risks like bias or hallucination.

Intrusion Detection & Security Controls

ZeroBounce AI systems are engineered with strong defenses against prompt injection, prompt priming, and model tampering. Our architecture prevents any unauthorized access or modification of prompts or models.

Transparency & Explainability

A built-in debug mode provides insights into the AI’s decision-making process, offering visibility into the data reviewed and increasing trust through explainability.

Data Handling & Protection

We do not ingest private or user-submitted datasets into our AI systems—only public data is used. Sensitive company data remains protected behind corporate firewalls and VPNs. Data deletion follows the same 30-day retention rule as the rest of the organization.

Threat Resistance & Risk Management

Threats like data poisoning or model inversion are not considered relevant due to the nature of our public data sources. However, all identified risks are documented and regularly assessed by our Quality Assurance team to ensure continued safety.

In-House AI Infrastructure

All AI models and infrastructure are developed and maintained in-house. We do not rely on third-party vendors, eliminating external exposure and ensuring full control over our AI ecosystem.

Leader in Email Validations

ZeroBounce is a leading online email validation system created to ensure that companies sending complex and high volume emails avoid deliverability issues. The system works by reducing and eliminating invalid, abuse, complaint, inactive, and spam-trap email addresses. These are email addresses that will either bounce or contribute to ruining your sending reputation. ZeroBounce also provides IP address validation and verification of key recipient demographics and has the ability to add missing information on certain emails, such as the name, gender and location of the owner.

We created a guide to help you navigate everything you need to be aware of when sending emails. It's the most comprehensive guide you'll find on the internet and we offer it for free, without any restrictions. You can read it here: THE COMPLETE GUIDE TO IMPROVE INBOX AND DELIVERABILITY

ZeroBounce is the most secure email validation system you can find. For us, the protection of your data comes first, so we don't cut cost in keeping it safe. We are registered with the BBB and approved for the EU Data Privacy Framework (DPF). We maintain enterprise contracts with all of our vendors, we operate our own data center and own our servers and hardware. We don't use third-party services, like Amazon, Azure, and other cloud services providers, to store your data.

ZeroBounce List of Sub-processors and Service Providers

What is a Sub-Processor?

A sub-processor is a third party engaged by a data processor to perform specific processing activities on behalf of a data controller. In the context of data protection and privacy regulations, such as the General Data Protection Regulation (GDPR), the following roles are defined:

• Data Controller: The entity that determines the purposes and means of processing personal data.
• Data Processor: The entity that processes personal data on behalf of the data controller.
• Sub-Processor: Any third party that the data processor uses to assist in processing the personal data.

In our case, in connection with ZeroBounce’s services such as email validation and list cleaning, a ZeroBounce customer (who acts as a data controller) outsources its data processing to a service provider (data processor - ZeroBounce). The service provider then hires another company (sub-processor) to perform some specialized task, like data storage. That third company becomes a sub-processor.

Under laws like the GDPR, data processors are required to obtain the controller's authorization before engaging sub-processors. Also, they must ensure that sub-processors adhere to the same data protection obligations as the original processor.

Due Diligence

ZeroBounce is committed to conducting thorough due diligence when engaging with third parties, ensuring that they are assessed prior to onboarding and as part of our annual risk management program.

We hold our service providers to strict contractual obligations, requiring them to process personal data solely for the purpose of delivering services to ZeroBounce. These contracts ensure that service providers comply with our commitments to ZeroBounce customers and adhere to applicable data protection laws.

Updates to this page

Given the global scope of our business and the large number of customers we serve, our business needs and service providers may change periodically.

For instance, we may discontinue a service provider to streamline and reduce the number of providers we use or add a new service provider if it improves our ability to deliver our email validation service.

We will regularly update this page to reflect any changes, including the addition or removal of service providers or sub-processors.
