Aligned with Grant Thornton’s IT strategy to lessen hardware reliance, the firm committed to Veeam’s Azure-based cloud storage solution, Data Cloud Vault. This plan offers robust ransomware defense, ensuring that systems are recoverable in disaster situations.
Future Aspirations: Welcoming AI
Grant Thornton’s investment in backup technology paves the way for embracing artificial intelligence technologies, especially agentic AI. Holmes aims to maintain a strong Microsoft 365 environment as the firm readies itself for future technological advancements.
