Nullify is the first complete AI AppSec engineer-in-a-box for small security teams
Nullify is reimagining product security from the first principles, enabling engineering teams to access world-class AppSec expertise. Nullify augments engineers and does tasks that had to be done by humans. Nullify saves you hours finding, prioritising and fixing security vulnerabilities across your entire stack. Building a mature security AppSec program is usually only for companies with top security engineering talent. Nullify is changing this by augmenting smaller teams with AI, without increasing headcount. One of the things that Gen AI is bringing to the table is identifying within the context of the application. Rather than just doing a scan and finding vulnerabilities, [Nullify is] prioritising and triaging the outcomes of its work. We need as much powerful tooling as we can to accelerate our identification of vulnerabilities...and prioritise based on context...Nullify is a huge assistance to the delivery of programs.

Make data-driven decisions faster
AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.
Large language model for reasoning and decision-making
Understand tasks, plan steps, generate responses
APIs, databases, external services the agent can call
Take actions beyond text generation (search, compute, write files)
Short-term (conversation) and long-term (persistent) memory
Maintain context across interactions and learn from past actions
Decision engine for choosing next action
Plan multi-step workflows and handle errors/edge cases
