In Halo, security is an ongoing process, not a one-time task. We regularly reassess our security measures to adapt to evolving threats and technology changes. We have recently achieved ISO 27001 certification which demonstrates our commitment to securing our customer’s data. We have an Information Security Policy and a set of other policies which outline our approach to information security. Protecting customer information is crucial, and we have implemented a range of security controls to achieve this:

Data Encryption & Backups

Sensitive customer data is encrypted, both in transit and at rest. This ensures that even if unauthorised access occurs, the data remains unreadable without the proper decryption keys. Regular backups of customer data are taken and these backups are kept secure. This helps in the event of data loss due to system failures, cyber attacks, or other emergencies.

Access Controls

Access to customer information is on a need-to-know basis. Strong authentication methods are used, like multi-factor authentication, to ensure only authorised personnel can access sensitive data.

Regular Software Updates

Software is kept updated, including security software, to patch vulnerabilities. Systems are regularly updated and patched to protect against known exploits.

Physical Security

We have secure physical access in place for our offices. This includes access controls, and environmental controls to protect against physical theft or damage.

Data Privacy

We clearly communicate our privacy policies to customers. We are transparent about how their information is collected, stored, and used. We obtain explicit consent for collecting and processing personal data.

BCP & Incident Response

We have a comprehensive Business Continuity Plan in place which has been approved by all areas of our business and is tested regularly.

An incident response plan has been developed and maintained to quickly and effectively address security incidents. This includes steps for identifying, containing, eradicating, recovering, and lessons learned from security breaches.

Security Training

Staff receive regular training on security best practices. This ensures they understand the importance of safeguarding customer information and are educated on how to recognise and respond to security threats.

Auditing & Penetration Testing

Regular security audits and reviews are conducted to identify and address potential vulnerabilities. This includes reviewing access logs, monitoring for unusual activity, and ensuring compliance with security policies.

Our Halo Vault is tested on an annual basis and any high or medium risk findings are investigated and resolved.
