How to choose a cybersecurity company

  1. Ask whether monitoring is staffed around the clock by the firm itself or by a partner.
  2. Ask for a sample assessment or penetration-test report with client details removed.
  3. Check experience with your industry’s rules (for example HIPAA, PCI DSS or CMMC).
  4. Ask what the firm does in the first hour of an incident, and whether that is in the contract.
  5. Ask for two or three references from clients of your size and industry, and call them.
  6. Get the scope, response times and price in writing before you sign, including how you leave and get your data back.

Questions to ask a cybersecurity company

  • Is your security monitoring staffed 24/7, and by whom?
  • Which frameworks do you assess against?
  • What do your reports include, and do you re-test after we fix the findings?
  • Do you handle incident response yourselves, and do you work with cyber insurers?
  • What access will you need to our systems, and how is it controlled and logged?
  • Which certifications do the people doing the work hold?

6 of 30 ranked cybersecurity companies post Saturday hours and 5 post Sunday hours. The highest-ranked open Saturdays are ISTT Inc. (#1), The 20 MSP (#2) and The 20 MSP (#11). Posted hours are office hours; many firms also run an after-hours support line for contract clients.

What Google rating do Glasgow cybersecurity companies have?

The median Google rating among 30 rated cybersecurity companies in Glasgow is 5.0★, with a median of 15 reviews. ISTT Inc. has the most, 130 reviews, and ranks #1. We adjust ratings for review count, so a few five-star reviews cannot top the list.

How does ITFirmsRanked rank cybersecurity companies?

Each cybersecurity company gets a 0–100 IFR Score from nine published factors, led by reputation (25%), review volume (15%), service focus (15%) and recency (10%). An IT firm with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out. Only IT firms with a confirmed service and 3 or more reviews, or a claimed profile, are ranked.

Do cybersecurity companies outside Glasgow count in this ranking?

Yes, if they are within 75 mi of the Glasgow city center, our service radius for cybersecurity companies. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.

Can cybersecurity companies pay to rank higher on ITFirmsRanked?

No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.

What does a cybersecurity company do?

Cybersecurity companies assess and protect a business’s systems and data: security monitoring, endpoint protection, penetration testing, compliance support and incident response.

How are cybersecurity companies in Glasgow ranked?

By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does cybersecurity, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.

Do we need a cybersecurity firm if we already have an IT provider?

Sometimes. Many IT providers include basic security tools; a security firm adds specialist work such as 24/7 monitoring, penetration tests, compliance audits and incident response. Ask your IT provider what they cover and where they would bring in a specialist.

What is the difference between a security assessment and a penetration test?

An assessment reviews your policies, settings and controls against a framework. A penetration test is an authorised, simulated attack that tries to exploit weaknesses. Both end with a written report and a list of fixes.

Can a cybersecurity firm help with compliance?

Many help organisations prepare for requirements such as HIPAA, PCI DSS, CMMC or SOC 2. They can advise and assess, but only an independent auditor issues a SOC 2 report, and compliance is ultimately your responsibility.
