The 19 most promising cybersecurity startups of 2023, according to VCs
- We asked a select group of VCs to name the most promising computer security startups in 2023 so far.
- They told us about a range of startups and why these companies are poised for success.
- Also see: 73 of the most promising startups of 2023, according to top VCs
As long as our world relies on technology for everything — our jobs, homes, money, healthcare — there will be cyber criminals finding ways to exploit the digital world for their own gain.
Cybersecurity was a hot area of venture investment during the pandemic but VCs have slowed investment in information security as part of an overall slowdown. That has made this segment a hot area for acquisition by larger corporations. The number of acquisition deals in the second quarter this year are up by 50% compared to the first quarter, PitchBook data shows.
Those working in the cybersecurity industry are often well paid, too, with jobs ranging from $100,000 to $400,000, according to the University of San Diego. That makes this a necessary technology and a good career.
So, when we asked dozens of VCs at the most successful firms to name the most promising startups of 2023 so far as part of our annual Most Promising Startups project, quite a few were security startups. We asked the VCs to name startups that are in their portfolios and ones that aren't. All data about money raised to date is approximate and from PitchBook, unless otherwise noted.

Amount raised to date: $10 million
Investor: Ted Schlein, Ballistic Ventures
Investor's relationship: Investor in this startup
What it does: Alethea offers a service that detects digital disinformation, protects companies from being targeted and offers mitigation if they fall victim.
Why it's hot in 2023: "The weaponization of the open internet – including malicious disinformation, misinformation, and social media manipulation – is one of the biggest issues we'll have to deal with over the next few decades," Schlein said. "Alethea's machine learning SaaS platform conducts multichannel analysis across billions of data points to identify disinformation and manipulation at its start, before it takes hold."
He also said that founder and CEO Lisa Kaplan "is a force" and the four-year-old startup is starting to win some big customers.
AppOmni: preventing cloud apps misconfiguration
Amount raised to date: $123 million
Investor: James Luo, CapitalG
Investor's relationship: None, not a portfolio company
What it does: AppOmni helps companies monitor the hundreds of cloud apps they use for potential misconfigurations or breaches.
Why it's hot in 2023: "SaaS applications are the new frontier of critical infrastructure for enterprises, and maintaining their security will only become more important," Luo said, adding that the startup's tech deeply integrates with software-as-a-service apps like Salesforce and ServiceNow, " which also contain an organization's most sensitive information."
Armis: protecting Internet of Things devices
Amount raised to date: $540 million, according to the company
Investor: Derek Zanutto, CapitalG
Investor's relationship: Investor in this startup
What it does: Armis sells a security platform that helps companies protect Internet of Things (IoT) devices from cyberattacks.
Why it's hot in 2023: "While the promise of IoT is reasonably well understood, enterprise adoption is far behind its full potential. Based on our conversations with industry leaders, the single biggest issue holding back larger scale IoT deployments is cybersecurity risk," said Zanutto. The startup attempts to address their concerns by helping them discover and identify all IoT devices connected to their network, identify threats, and automatically remove suspicious devices.
Blockaid: stealth Web3 app security
Amount raised to date: Undisclosed
Investor: Chengpeng Mou, CapitalG
Investor's relationship: None, not a portfolio company
What it does: Blockaid is a startup, still in stealth, working on application security for Web3 applications that rely on blockchain technology.
Why it's hot in 2023: "Web3 security is a well documented problem: attackers have stolen tens of billions worth of digital assets in the last few years. Lack of users' trust and safety has limited the potential and adoption of blockchain technology," said Mou, adding that he's impressed with the startup's vision, technology and leadership team.
Chainguard: securing the software supply chain
Amount raised to date: $50 million, according to the company
Investor: Thomas Krane, Insight Partners
Investor's relationship: None, not a portfolio company
What it does: Chainguard examines and certifies that the software supply chain, bits of code developers will acquire from others as they write new software, is free from malware.
Why it's hot in 2023: "Modern software development is best characterized as the process of assembling ready-made components rather than building from scratch. While this leads to much faster development cycles, it also creates cyber exposure if downstream components have been compromised," said Krane.
Krane adds that Chainguard is taking "a novel approach" to this security issue. It allows developers to third-party and open-source software before using it themselves.
Cinder: help for trust and safety operations professionals
Amount raised to date: $14 million, according to the company

Why it's hot in 2023: "The work of trust and safety teams is too important to be supported by a patchwork of tools," said Ittelson. "In 2023 Cinder made massive strides in building its platform and proved it is a solution for scale, supporting many global customers with over tens of millions of daily active users."
Ittelson added that the tool can help companies adhere to the European Union's Digital Services Act, fend off AI and robotic threats and the team includes people from Meta's Trust and Safety team, Google, Match Group, and academia.
