Cybersecurity Awareness Month: How Zynk keeps your integration data secure

October is Cybersecurity Awareness Month, a global reminder to protect data, systems and privacy from cyber threats. For businesses that connect their accounting, e-commerce, CRM and ERP systems, one question matters more than most: how secure is the data moving between them?

Every integration handles valuable information, such as customer details, orders, invoices, stock levels and financial records. Choosing a secure data integration partner is therefore a security decision as much as a technical one. Here is how Zynk protects your data at every stage.

Certified to the international standard for information security

Zynk is ISO 27001 certified. ISO 27001 is the internationally recognised standard for information security management systems (ISMS), and certification requires rigorous assessment of security controls, risk management, data handling and internal governance.

ISO 27001 is not a one-off achievement. It requires regular audits and reviews, so our systems and processes stay compliant and aligned with evolving best practice. For customers in regulated industries, it also reduces due diligence, because you can rely on our independently audited ISMS when assessing your own supply chain.

Zynk is also compliant with UK and EU GDPR, so personal data is handled lawfully and responsibly across every integration.

Security built into every integration

Encryption in transit and at rest

Your data is encrypted while it moves between systems and while it is stored. Combined with secure transfer protocols, this means information stays protected throughout its journey, not just at the start or the end.

Least-privilege access

Zynk integrations are designed using secure APIs, mutual authentication and least-privilege principles. Systems share only the data needed for their intended purpose, and only with authorised endpoints.

Secure credential storage

When you connect a system through Zynk Workflow, the Connection Manager stores the credentials needed to communicate with that system's API securely. Many connectors, including Xero, use OAuth 2.0 authorisation, so access is granted through the platform itself.

Full visibility with logs and monitoring

Every integration includes audit logs, notifications and monitoring. You can see what has run, when, and whether anything needs attention, which makes it easier to spot unusual activity and meet your own compliance requirements.

File-level encryption with PGP

For businesses exchanging sensitive files, Zynk's PGP connector encrypts and decrypts files automatically as part of a workflow, protecting data exchanged with partners, suppliers and banks.

Deployment options that fit your security needs

Every business has different security requirements, so Zynk offers a flexible deployment model. Our cloud solution is hosted on Microsoft Azure, providing enterprise-grade security and reliability. For businesses that prefer to keep data within their own environment, Zynk can also be deployed on-premise.

Independently tested by enterprise security teams

Security claims matter most when they are independently tested. Zynk has passed a comprehensive security audit carried out by Amazon's own security team and PwC as part of our Amazon integration.

The audit examined authentication protocols, data encryption, access control and resilience at scale, as well as the processes and policies behind the technology. Passing it again confirms our ability to operate to enterprise security standards.

Secure processes behind the platform

Technology is only part of the picture. Our security programme also covers how our team works day to day, including:

• Restricting administrative access to critical systems to those who need it for their role

• Encrypting all critical endpoints

• Security and privacy training relevant to each role

• Security risk screening before anyone is granted access

• A documented incident management process, with every incident recorded and investigated

• Business continuity and disaster recovery planning

• Everyday practices such as screen locking, clean desks, secure disposal of sensitive materials and authorised devices only

Our support is secure too. Where remote support is needed, we use Zoho Assist exclusively, as it meets our security and compliance requirements. Credentials shared with our team are encrypted and cannot be viewed or retrieved in plain text.

Transparency through our trust centre

We believe you should be able to verify our security for yourself. Our Trust Centre sets out our security posture, policies and controls, including our access control and business continuity policies. It is a useful resource for anyone completing a vendor risk assessment.

What to ask your integration provider

This Cybersecurity Awareness Month is a good time to review the suppliers who handle your data. When assessing any integration platform, ask:

• Are you ISO 27001 certified and GDPR compliant?

• Is data encrypted in transit and at rest?

• How are system credentials stored and protected?

• What logging and monitoring is available?

• Can I review your security policies and controls?

If a provider cannot answer these clearly, your data may be more exposed than you think. For more guidance, read our blog on the five questions to ask before any data integration project.

Security every day, not just in October

Cybersecurity Awareness Month is a valuable reminder, but at Zynk, protecting your data is part of how we work every day. From ISO 27001-certified processes to encrypted, monitored integrations, we make integration simple, secure and scalable.
