Frequently Asked Questions

Can CTI Technology take over our IT if our environment is a mess or undocumented?

Yes. Most clients come to CTI Technology with chaotic, outdated, or poorly documented systems. Our onboarding team performs a full environment assessment, creates complete documentation, stabilizes any critical risks, and implements best-practice security within the first 30 days – all without interrupting your operations.

Can CTI Technology help our business stay compliant with industry regulations like HIPAA or NIST?

Absolutely. Our technicians are HIPAA-certified and trained in PHI/EPHI protection, NIST standards, data-handling protocols, and secure identity management. We build compliance into your daily operations so audits, reviews, and security questionnaires are simple and stress-free.

Can CTI Technology work with our internal IT staff or do you replace them?
