What to ask an IT provider in West Sussex

Use these questions when evaluating any IT support provider in West Sussex, regardless of size or certification status.

  1. How do you demonstrate that our systems stay protected between audits - not just at certification renewal? Verified IT support providers use continuous monitoring, not one-off assessments. Ask to see a live dashboard or a recent compliance report before signing.
  2. Which cybersecurity certifications do you hold, such as Cyber Essentials Plus or ISO 27001, and are they current? Certifications expire. Always ask for the certificate date and the issuing body, and check whether the scope covers the services you are buying.
  3. What is your guaranteed response time for a critical incident, and who is responsible out of hours? Response SLAs vary widely. Confirm whether the SLA covers resolution or acknowledgement only, and ask who you actually reach at 2 am on a Sunday.
  4. How do you handle a security breach - who do you notify first, and what does your recovery process look like? UK GDPR requires breach notification within 72 hours. Your IT provider should have a documented incident response plan and be willing to share it.
  5. Can you share references from clients in a similar sector or of a similar size? A provider experienced in your industry already understands your regulatory context, common threat patterns, and the compliance questions your clients ask.
  6. What is included in your monthly fee, and what would be charged as an extra? Common add-on costs include out-of-hours callouts, additional users, hardware replacements, and advanced security tools. Get the full scope in writing before you commit.
