      Review averages are so high because they buried mine and I'm sure others. They really burned their investors and showed their lack of confidence in the internal sell off. Momentum was going so good. Only to be smashed by internal sell offs. Hello, average salary for a CEO in the U.S. is $885,000. I guess at big bear they think it should be $10M in stock before they even execute and make profits. That's why under 20% is institutional. You have to care about external investment as much as your own. Disgraceful.

      There is (hopefully soon to be "was") one other review here which is from someone who was confused about which NuWave Solutions this company is. They don't sell appliances, they're a software consulting company, and they do a damn good job of it too.

      Kevin Sheely's Review Sourced from Google

      Had the extreme displeasure of wasting my time and money with these clowns. While interviewing for a state job, I was offered a very competitive salary. Two days before my start date I was informed by the HR manager Himanshu that the new offering would be$10,000 per year less.Not only did they expect me accept this ludicrous offer, they also made me pay for my own background checks. Now that there is no serious offer on the table, they don’t want to compensate me for the checks.I have made several offers to compromise, but I think that their idea of compromise is for me to smile and accept $10,000 less each year. I suggested a signing bonus to offset to difference. I offered a different salary. I offered to let them find a way to solve the problem, radio silence.This is a scam, or at the very least a bunch of lazy, inept individuals who have no concern for their employees.As a temp agency, they make money when we make money, so it’s supposed to be mutually beneficial. I’m glad I smelled this from a mile away, because if I’m having this much trouble now, what do I have to look forward to in the future? Paycheck problems, Tax evasion? Who knows? Crisis averted?

      I was offered a Data Entry Clerk and went over and submit all the information, literally everything and now they said position withdrawn. No longer position exists. Such a waste of time, energy and big loss was I gave all my personal sensitive information. I talked to Raghu Nandan Sharma @ Gurleen Kaur plus Navneet Kaur. I would never apply company like this again. I will also report to security compliance company or maybe I should call Data Theft. Anyone looking this review if this happened to you let me know. Or anyone working there in Person at U.S office please tell me this is valid company so I can breathe 🧘

Frequently Asked Questions

What is a cybersecurity company?

A cybersecurity company is a specialized IT service provider that fortifies a business’s IT ecosystem against technological threats. These include hacking, malware, phishing, and data breaches. It achieves this by implementing advanced data encryption, threat detection, and disaster recovery strategies. 

Ultimately, the goal of a cybersecurity firm is to minimize risks, ensure compliance, and enable the business to recover quickly in the case of an attack. 

How do cybersecurity providers help businesses protect data and systems?

Cybersecurity providers help businesses protect data and systems by auditing and testing networks, endpoints, and cloud environments to identify and resolve vulnerabilities. It also implements proactive security measures tailored to an organization’s system. These include installing firewalls and antivirus software, implementing zero-trust architecture, and monitoring systems 24/7. 

Moreover, cybersecurity companies safeguard the human layer of defense by providing training, access point control, and multi-factor authentication. 

Which industries benefit most from cybersecurity services?

The healthcare, finance, legal, and government industries benefit most from cybersecurity services. These sectors handle highly sensitive data, exposing them to cyberattacks. They also have stringent industry regulations, requiring advanced security practices.   

Additionally, industries that rely on digital systems to conduct business gain from cybersecurity services, as an attack may lead to significant financial losses. Examples include eCommerce, manufacturing, and tech companies.

  • Security audits and assessments

  • Data encryption

How much do cybersecurity services cost in 2025?

On average, cybersecurity costs about 5.6% to 20% of a business’s total IT budget in 2025. Factors that impact price include security type, industry-specific regulations, and company size.  

Additionally, system strength, level and type of protection, existing tech stack, and type of attacks your business experiences can also affect costs. 

How quickly can a business strengthen security with a cybersecurity partner?

With a cybersecurity partner, businesses can strengthen their security within a few days or years, depending on the severity of their situation. For instance, a company facing an active ransomware attack can immediately experience cybersecurity benefits, as the provider contains the breach, negotiates with the attackers, and prevents recurrence. In contrast, an enterprise with legacy systems seeking an end-to-end security posture may take months or years. 

EY reports that organizations detect and resolve cyber incidents within 6 months. However, the timeline may be shorter for businesses with mature security practices. Its survey also found that these businesses are more likely to outsource their cybersecurity function to third-party specialists. 

What should you look for when hiring a cybersecurity company?

When hiring a cybersecurity company, look for the following: 

  • Proof of expertise. For instance, cybersecurity certificates, industry awards, and memberships in established organizations (e.g., National Security Alliance and ECSO). 
  • Up-to-date knowledge. Evaluate its tech stack, blogs, and latest projects. 
  • Experience in your niche and tech stack. Look at its case studies and list of technologies. 
  • Strong client relationships. Examine client testimonies and reviews, and see if there are long-term engagements. 
  • Transparent and proactive approach. Interview client references and the agency. 
  • Cultural alignment. Observe how the agency interacts and communicates with your team. 

What red flags suggest a cybersecurity provider may not be reliable?

Here are some red flags that suggest a cybersecurity provider may not be reliable: 

  • Outdated security practices 
  • Overpromising results without evidence to back up claims (e.g., 100% cybersecurity) 
  • Significant number of negative reviews on third-party websites 
  • No information on its team members, tech stack, recent projects, methodologies, or industry certifications 
  • Reliance on off-the-shelf and AI tools without vendor risk management practices 
  • High employee dissatisfaction rate and insufficient employee training

What key questions should you ask before signing a cybersecurity contract?

Before signing a cybersecurity contract, ask the following key questions to ensure the right fit: 

  • Can you share case studies or examples of projects within my industry or with a similar scope? 
  • What does your vulnerability assessment and proactive cybersecurity process look like?
  • How do you handle integration with existing systems and ensure compliance? 
  • How do you mitigate and manage security risks and data breaches during deployment? 
  • What are your post-implementation services? 

How does working with a cybersecurity company differ from internal IT teams?

Internal IT teams are responsible for managing a business’s IT infrastructure — from maintaining the company website to installing office tools. While cybersecurity is a part of their main role, their resources are often spread across many responsibilities, limiting their capacity for advanced security measures.  

On the other hand, cybersecurity companies exclusively focus on protecting data and systems. They provide specialized expertise, enterprise-grade tools, and proactive strategies to defend against sophisticated threats. Unlike most internal teams, they offer continuous 24/7 monitoring and rapid incident response, ensuring businesses stay protected even outside regular working hours. 

Which tools, monitoring platforms, and frameworks do top cybersecurity companies use?

Top cybersecurity companies use the following tools, monitoring platforms, and frameworks: 

  • Endpoint Security: CrowdStrike, SentinelOne, Okta, Duo Security, 1Password, Keeper 
  • Remote Access & Zero Trust Networking: NordLayer, Tailscale 
  • SIEM: Splunk, IBM QRadar, Microsoft Sentinel 
  • MDR/XDR: Arctic Wolf, CrowdStrike Falcon Complete, Palo Alto Cortex XDR
