Investor Considerations for Cybersecurity Startups

Potential To Scale, Lean R&D

Scalability will always be one of the most critical factors for investing in a successful startup. When there are growth opportunities, startups should and usually do capitalize on them.

Investors are also looking for startups that can continue to improve their products without the need for substantial capital investment. Lean research and development (R&D) show efficiency, even with limited resources. Investors can evaluate how the product and business model evolve before investing more capital. This fact makes any startup’s quality of personnel and leadership a critical factor in the organization’s success.

A Solid Business Plan

Another factor investors have always looked for is an air-tight business plan. They want assurance that there is a marketable problem that the product solves. Investors also want to see financial reports and revenue growth projections backed up by market analysis.

Compliance Mindset

Regulatory compliance, such as HIPAA, GDPR, and CCPA, is essential for organizations collecting and protecting user information, including virtually all enterprise-level companies. Investors will be looking for startups that can ensure customers will maintain compliance.

Remote Work Experts

Remote work is and will continue to be, for the foreseeable future, a top-of-mind factor for venture capitalists. Even with vaccines, a largely remote workforce is likely here to stay.

Startups that can immediately impact the remote worker ecosystem will garner much attention. Specifically, startups with SaaS (software-as-a-service), those that provide automation, and products that include endpoint protection will fall into this category.

As organizations, clients, and end-users increasingly rely on cyberinfrastructure, the need to protect these systems will only deepen.

Given the relative newness of IT industries at large, cybersecurity remains a budding marketplace with plenty of opportunities for new vendors. Some of the best cybersecurity companies are longtime technology stalwarts. Still, many have proven the right solution and service can catch on fast with eager investors ready to help worthy startups scale.

Most Popular Cybersecurity Startup Solutions in 2023

  • Application Security
  • Attack Surface Management
  • Cloud Security
  • Cyber Asset Management
  • Digital Forensics and Incident Response
  • Identity and Access Management
  • Governance, Risk, and Compliance
  • Risk Scoring and Assessments
  • Software Development Lifecycle (SDLC)
  • Threat Detection (EDR, XDR)

Endpoint Security and Protection Against Ransomware

Endpoint security, including traditional endpoint detection and response (EDR) and increasingly, its advanced iteration, extended detection and response (XDR), continue to be in high demand in light of the boom in remote work.

Products like EPP, EDR and XDR solutions secure the devices spanning a remote ecosystem and will continue to be invaluable. The healthcare segment alone saw significant investment in cybersecurity due to the adoption of telehealth and teleworking models.

Most Popular Headquarters for Cybersecurity Startups

The United States, Israel, Canada, and the United Kingdom continue to be popular national locations for cybersecurity startups, with most of the funding directed between the first two.

Within the United States, the San Francisco Bay Area remains the hottest region for startups. The second-largest contingent of cybersecurity startups is a continent away from Palo Alto, in New York City. The industry newcomers benefit from the proximity to partnerships, skilled IT personnel, and funding opportunities.

Though it’s hard to compare to the presence of San Francisco and New York, other U.S. cities holding multiple top contenders this year include:

  • Atlanta, GA
  • Austin, TX
  • Boston, MA
  • Chicago, IL
  • Dallas, TX
  • Los Angeles, CA
  • San Diego, CA

Top Startup Selection Criteria

For this list we’ve generally favored companies that have been around for 5 years or less and are still in their first few rounds of funding, although older companies receiving renewed investor interest have also made this list. Sources include our observations and analysis of the cybersecurity market and startup databases such as Growjo and Crunchbase.

Our top startups are independent companies with innovative cybersecurity products or services, with a viable business plan with evidence of scalability.

We look for evidence of solid growth and traction, but once companies become too big to be called “startups” anymore — more than $100 million in revenue has been our primary criteria for “graduation” — we move them to our “graduated” list below.
