16 trending application security startups in 2025

What are application security startups?

Application security startups are new companies that build specialized tools to protect software from hackers and cyber attacks. They help businesses spot weak points in their apps, catch security bugs before they cause problems, and build stronger defenses against the latest hacking tricks. Unlike old-school security companies that focus on network protection, these startups zero in on making the apps themselves harder to crack – whether they’re running on phones, computers, or in the cloud.

Socket

Founded in 2010, Socket is a cybersecurity startup that protects companies from risks related to open source software dependencies. Open source libraries and components are included in nearly all applications today. While convenient, vulnerabilities or backdoors can secretly hide in these dependencies.

The Socket platform continuously scans for issues in open source packages – before they become problems. Using intelligence and analytics, their technology spots suspicious code changes, new vulnerabilities, and other red flags. Software teams get notified to rapidly remove or respond to any risks.

ArmorCode

Founded in 2020, ArmorCode is a company aiming to give all software teams access to powerful security tools, no matter their size or resources. Their goal is bringing enterprise-grade application security to organizations big and small. Typically, smaller dev teams building modern software lack time and budget to properly address vulnerabilities.

ArmorCode wants to change that by providing easy-to-use automated solutions for finding and fixing security defects throughout the development process. Their products instrument code and use specialized analysis to identify high-risk areas in need of hardening. Detailed guidance then helps developers remediate any flaws across cloud, web, open source, IoT, and mobile applications. Any team can start building strength in their software.

Operant

Founded in 2020, Operant is a cybersecurity company that protects applications while they are running. They offer various solutions to give more visibility and control over a software system’s APIs, microservices, and user access permissions.

Operant’s tools track communications between the different components of complex applications to identify risks. This runtime insight exposes potential attack vectors and suspicious user activities that traditional security tools miss.

Heeler Security

Founded in 2023, Heeler Security is a startup focused on application security solutions to help organizations defend against emerging cyber threats. Their products assist companies in protecting business-critical apps and data.

As more infrastructure moves to the cloud, traditional security controls miss vulnerabilities unique to modern web and mobile apps. Heeler Security combines intelligent automation with human insight to safeguard these complex environments better.

StackHawk

Founded in 2019, StackHawk is a company that helps software engineers find and fix security vulnerabilities in their applications during development. Their platform allows teams to automatically scan code for bugs at any point in the coding process, whether incomplete or ready to deploy. This saves time hunting issues later.

StackHawk was founded by engineers with deep backgrounds in security and DevOps. This insider expertise shaped their product philosophy that app security should empower developers, not block them. Their tool seamlessly fits application testing workflows.

Ory Corp

Founded in 2019, Ory Corp is a company focused on improving internet security and privacy. Their mission is to make the digital world more secure for all users through new products designed to fix vulnerabilities.

Issues like identity fraud, hacking, and data exploitation are growing fast as life and business move increasingly online. Ory aims to tackle these systemic risks not just for enterprises but for regular internet users as well.

Legit Security

Founded in 2007, Legit Security offers software that helps companies manage and improve the security of their applications across the entire software development life cycle. Their platform secures code at every stage, from writing to testing to deployment in the cloud.
