Application Security Testing
Human-led, AI-Powered Application Testing
, our proprietary AI, powers every engagement. Trained on 30,000+ UltraViolet tests. Mapping attack surface, running specialist tests in parallel, pointing pentesters at what matters next.Practitioners stay in control. Testing gets faster, broader, and smarter every year.
Get Ahead of Application-Layer Risk
From open-source code to AI-assisted development, the application layer is where modern threats are born and where many security programs fall behind.
UltraViolet Cyber delivers offensive testing, architecture analysis, and secure development strategy as part of a unified security operations model. Whether you’re deploying to cloud-native stacks or delivering regulated software at scale, we help you find and fix risk before attackers do.
Every engagement is powered by Solstice, a proprietary AI platform trained on six years and 30,000+ UltraViolet engagements. The result: faster reconnaissance, broader coverage, and findings backed by institutional knowledge no competitor can replicate.

The AI Platform Inside Every UltraViolet Engagement
Solstice is our proprietary AI platform. It's not a product you buy. It's not an autonomous scanner. It's the engine our pentesters work with every day, built by UltraViolet AppSec practitioners, trained on our own knowledge base, and designed to amplify human expertise rather than replace it.
Four interconnected capabilities operate across every engagement.
01. PRE-TEST INTELLIGENCE
Automatic attack surface mapping
Solstice parses live testing traffic and ingests application context to catalogue the attack surface, construct a threat model, and generate a structured test plan, all before the first briefing call ends. Our practitioner reviews, enriches, and approves.
02. PARALLEL EXECUTION
Specialist agents running concurrently
From the test plan, specialist agents run injection, authorization bypass, authentication, and 30+ other vulnerability classes in parallel — while our practitioner focuses on business logic, trust boundaries, and chaining. Practitioners direct agents and approve or dismiss findings with rationale.
03. REAL-TIME GUIDANCE
Just-in-time coverage recommendations
Solstice watches the practitioner's testing as it happens and surfaces contextual next-step suggestions — flagging coverage gaps and identifying endpoints that share characteristics with confirmed findings before the engagement window closes.
04. ENGAGEMENT BRAIN
A persistent knowledge graph and automatic report drafting
A listener agent captures every action into a knowledge graph that's queryable in plain language. At the end of the engagement, a narrator agent reads the graph and produces a structured draft report with HTTP evidence, attack narrative, and prioritized remediation. Our practitioner refines and delivers.
When our offense gets better, everything gets better.
Application testing doesn't exist in isolation. When Solstice surfaces a new authentication bypass during your engagement, that pattern feeds detection engineering. When our practitioners dismiss a false positive, that signal sharpens the entire system. UltraViolet's offense and defense run under one roof. AppSec testing isn't a point service, it's the input that makes your detections, your defenses, and your SOC posture continuously stronger.
That closed loop is what we call the Power of Purple, and it's why we built Solstice as part of our operations rather than as a standalone product.
What We Deliver
Application-layer testing led by experienced practitioners and amplified by Solstice.
Our team runs business logic, chaining, and post-auth work that generic scanners miss.
Solstice handles the specialist coverage in parallel (SQLi, XSS, IDOR, prompt injection, and 30+ more vulnerability classes).
Solstice maps your attack surface from live traffic (site map, threat model, test plan) before our kickoff call ends.
Our practitioners use that context to evaluate how your software performs across production-like environments, multi-cloud infrastructure, and CI/CD workflows, so you can prioritize the right risks.
We help teams integrate secure development practices through threat modeling, architectural reviews, and training tailored to how your software is built and delivered.
Findings from every Solstice augmented engagement feed back into the strategy work, so recommendations reflect what actually broke in your environment.
Find the best test for the job.
Our services cover the full spectrum of application security, from hands-on testing and code-level analysis to secure development strategy.
Application Penetration Testing
Identify vulnerabilities across web, mobile, and cloud applications through tailored, real-world attack simulations.
Red Teaming
Simulate sophisticated attackers to expose gaps across the full application kill chain, including identity, code, and cloud.
Thick Client Testing
Assess complex desktop and legacy client applications for security weaknesses across platforms.
Network Testing
Evaluate network-layer exposure across internal, external, and application-adjacent systems.
Cloud Risk Assessments
Analyze configurations, identity policies, and deployment risks across AWS, Azure, GCP, and hybrid environments.
Architecture Risk Analysis
Cloud & Container Security
Assess container images, orchestrators, and runtime configurations to prevent lateral movement and data exposure.
Software Security Training
Static and Composition Analysis (SAST/SCA)
Embed security into your SDLC by analyzing code and open-source components for known/emerging risks.
Threat Modeling
Proactively map attacker paths and design secure architectures before code is written.

Securing fast-moving cloud-native environments, CI/CD automation, and customer-facing applications at scale.
HEAR FROM OUR CUSTOMERS
This has been the cleanest pentest in terms of scheduling, planning, execution, and remediation in my experience at this company. Better than expected. If you expect other pentests to be this good, prepare to be disappointed.
