What are investors looking for in cybersecurity startups in 2021?

Some of the biggest factors venture investors are looking for in startups are uniform across the board for any technology vertical. However, there are some factors that are unique in 2021, namely due to the pandemic.

Startups with scalability and lean research and development

Scalability will always be one of the most important factors for those looking to invest in a successful startup. When there are opportunities for growth, startups should be ready to capitalize on them immediately.

Investors are also looking for startups that can continue to improve their products without the need for substantial capital investment. Lean research and development show efficiency, even with limited resources. This will also allow investors to watch the product and business model evolve over time before investing even more capital.

Startups with a solid business plan

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


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

Startups who can support remote work

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

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

How Covid-19 impacted cybersecurity

The impact of Covid-19 on the cybersecurity industry is reportedly expected to hit $230 billion this year, exhibiting a CAGR of 12% during the forecast period. This report also projected that because of the boom in remote work, endpoint security is expected to grow at the highest rate of any cybersecurity segment.

Products like Endpoint Protection Platforms (EPP) and Endpoint Detection and Response (EDR) solutions secure the devices spanning a remote ecosystem and will continue to be invaluable. The healthcare segment, in particular, will likely see the largest investment in cybersecurity due to telehealth and teleworking models.
