ThirdEye helped analyzing data and recommending architecture for enhanced analytics. They understood our business needs really well and went above and beyond to deliver what we were looking for.
Software Development Review from Kumar Mankala

I did a voice study for them almost two months ago, still waiting for my payment. I contacted them multiple times and they don't even respond. What a joke.

C Parkin's Review Sourced from Google
They are very professional, punctual and honest. We have had multiple projects with them in the past (including new server installations multiple times) and it's been flawless each and every time. They don't try and $$ gouge, they are upfront and honest. Love my IT guys that I work with one on one. Would highly recommend ISO for anyone looking for a new IT source.

IT Services Review from Katie Overman, PMP
I have worked with Glacis at two different organizations, and recommended them to other small businesses and nonprofits as a reliable, flexible organization staffed with experts who both know their stuff and have the soft skills to successfully work with our nontechnical staff. We have not faced an IT problem that the Glacis team hasn't been able to solve in a functional, cost effective way.

Toni J's Review Sourced from Google
Service guys and operators are kind and good at what they do. Since being taken over, the Acct Manager we deal with is rude, short and acts like everything is a problem unless she thinks she's going to get a sale. So kind and responsive at that point, the rest of the time, No.
Jim Bachaud's Review Sourced from Google
One of the largest and fastest growing IT services providers in the country. Knowing I can call the support desk 24/7 for solutions, when we deal with real deadlines with real consequences, makes a huge difference for me as well as our staff.And, for the most part, we don't have to call the support desk because everything works. The only times I have to reach out is when we hire a new person, or add a new service or license. They are very pro-active and results oriented.
Sean Pratt's Review Sourced from Google
The company we hired to handle the IT services for our small business sold out to these guys and the service we received plummeted. We were paying a ridiculous monthly fee for managed IT services yet the few times we'd actually need help we would end up on hold forever and not receive calls back when promised. It took them almost two weeks to get a computer connected to our network and over a week to connect a new check scanner.**Edit: They were helpful with the offboarding process to our new IT company. The owner of the old company we had originally contracted with did reach out, which was appreciated. I really still feel that the IT services we were receiving were sub-par.

James Hanley's Review Sourced from Google
My office network crashed on Friday. VQIS was there the same day to diagnose the problem. They got it up and running the same day, and recommended a couple upgrades to insure it would not continue happening. They were out the following Monday to repair/replace the equipment.A+ for these guys, all of them know what they are doing and they had me up and running within hours of the initial phone call.THANK YOU VQIS!
Donna McCoy's Review Sourced from Google
Top notch all the way! Professional yet personable. Extremely good at what they do (Mac or PC) and they explain everything in a way I can understand. VQIS does remote monthly maintenance on my work laptop (windows), as well as takes care of my family’s non-work iMacs when we have issues. I trust them so much that I’m willing to drive an hour and a half to bring them my computers if they need to fix hardware issues. Fast turn around with status updates along the way. All with a friendly attitude and a great sense of humor, which is always a plus!

Cybersecurity Incident Response Companies in the United States FAQs
What makes cybersecurity incident response companies in the United States different from competitors?
Cybersecurity incident response companies in the United States stand out because they combine speed, expertise, and proven systems.
They have 24/7 monitoring, clear playbooks for handling attacks, and teams trained to respond fast to ransomware, phishing, or data breaches. What really sets them apart is their ability to reduce downtime, recover systems quickly, and prevent future attacks through strong post-incident analysis.
How experienced should US cybersecurity incident response companies be?
US cybersecurity incident response companies should have at least 5–10 years of hands-on experience dealing with real incidents across finance, healthcare, and government sectors.
Experience matters because every breach is different. A seasoned company has seen a wide range of threats and knows how to act under pressure without making mistakes that could cost time or data.
What certifications should cybersecurity incident response companies in the United States have?
Cybersecurity incident response companies in the United States should hold certifications that prove technical skill and data security standards. The most common are ISO 27001, SOC 2 Type II, and CREST.
Team members should hold individual credentials such as CISSP, CEH, or GIAC (GCIH, GCFA, GCIA). These show that the company and its experts meet strict global standards for handling and protecting sensitive information.
How do cybersecurity incident response companies in the United States stay updated with industry changes?
Cybersecurity incident response companies in the United States stay up to date by tracking threat intelligence feeds, joining cybersecurity alliances, and attending major conferences like Black Hat and DEF CON.
They also partner with government and private security networks such as CISA and FS-ISAC. Continuous training and real-world simulations help their analysts adapt quickly to new attack methods and technologies.
What tools and technologies do cybersecurity incident response companies in the United States use?
Cybersecurity incident response companies in the United States use Security Information and Event Management (SIEM) platforms like Splunk or IBM QRadar to detect attacks.
For investigation, they rely on endpoint detection tools such as CrowdStrike or SentinelOne. They also use forensic software like EnCase or FTK, and SOAR platforms to respond faster.
Encryption, sandboxing, and threat-intel platforms are also part of their toolkit.
How do US cybersecurity incident response companies ensure quality results?
US cybersecurity incident response companies follow structured frameworks such as NIST 800-61 and MITRE ATT&CK. Every incident is logged, reviewed, and tested to confirm that systems are secure before closing the case.
Top firms also run post-incident reviews to find root causes and update their response playbooks. Regular audits, red-team exercises, and client feedback keep their methods sharp and reliable.
