Because breaches aren't an option.

Don't let your workflows work against you.

PurpleLotus finds business logic flaws and multi-step vulnerabilities that traditional tools miss — without drowning you in noise. Built for open source teams who ship fast and can't look away.

Why PurpleLotus

Open source is the new attack surface.

96% of codebases contain open source components
8× supply chain attacks YoY since 2020
742 avg. days to detect a supply chain breach

Modern software is assembled, not written. Every package you pull is a door you're leaving ajar. Traditional scanners see the doors — PurpleLotus sees who's walking through them and how they chain attacks together.

We find business logic flaws and multi-step vulnerabilities that automated tools fundamentally cannot detect. The kind that turn a low-severity misconfiguration into a full supply chain compromise.

Our researchers have been there. They've exploited the same classes of bugs in production at scale. That experience is why Microsoft and GitHub trust us enough to list us in their halls of fame.

"Because breaches aren't an option. Don't let your workflows work against you."

Ongoing supply chain attacks this month.

Pulled automatically from the GitHub Advisory Database — real advisories affecting npm, PyPI, Go, RubyGems, Maven, crates.io and GitHub Actions, updated daily. No LLM in the loop: names and version ranges come straight from the advisory record.

These results are sourced from the public web — specifically the GitHub Advisory Database — and are surfaced here automatically without manual verification by PurpleLotus. Advisory data can be incomplete, disputed, or updated after this page was generated. Always confirm affected/patched versions against the linked upstream advisory before taking action on your own systems.

SecureCI/CD — supply chain security that ships with your code.

Protect your GitHub CI/CD pipelines with real-time threat detection, automated security checks, and robust access controls for a secure software lifecycle. PurpleLotus integrates directly into your pull request workflow — no dashboard-switching, no alert fatigue.

We scan for dependency confusion, typosquatting, malicious package injections, secrets leakage, and pipeline privilege escalation — the exact vectors attackers use to poison open source at the source.

Case Study · Why It Matters

The SolarWinds Playbook

The 2020 SolarWinds attack inserted malicious code into a software update, impacting thousands of organisations including US government agencies. Attackers didn't break in — they were invited through a poisoned build pipeline.

SecureCI/CD is engineered specifically to detect and block this class of supply chain attack before your update ships to users.

01 — Detection

Dependency Poisoning

Real-time scanning for dependency confusion, typosquatting, and malicious package injections across npm, PyPI, Maven and Go modules at every PR.

02 — Pipeline

CI/CD Integrity

Monitors GitHub Actions workflows for secrets exposure, permission escalation, and unpinned third-party actions across your entire organisation.

03 — Response

PR-Level Remediation

Automated PR comments with reproduction steps, fix suggestions and severity scoring — so developers act without ever leaving GitHub.

Services

Penetration Testing Services

01

Network Penetration Testing

Simulate attacks to uncover network vulnerabilities. We go beyond automated checklists to find the chained multi-step paths adversaries actually exploit in the real world.

02

Application Penetration Testing

Test web and mobile apps for security flaws — business logic bypasses, authentication weaknesses, and deep injection vulnerabilities that scanners consistently miss.

03

Social Engineering Testing

Assess susceptibility to phishing and social attacks with realistic simulation campaigns that surface your human attack surface before adversaries find it first.

FAQ

FAQs — PurpleLotus

What types of pentesting does PurpleLotus offer? +
We offer web, mobile, cloud, network, and CI/CD pentesting tailored to modern threat landscapes — with a particular focus on supply chain and open source pipeline security.
How are PurpleLotus pentests different from others? +
We go beyond checklists — focusing on real-world exploitation paths, misconfigurations, and chained logic flaws. Our researchers find the paths that automated tools fundamentally cannot detect.
Do you provide a detailed vulnerability report? +
Yes. Every engagement includes a prioritized, developer-friendly report with reproduction steps, CVSS scoring, and actionable remediation guidance written for your specific stack.
Are your tests manual or automated? +
We combine automated scanning with expert-driven manual testing to uncover deep vulnerabilities. Automation finds the breadth; our humans find the depth and the business logic flaws.
Is PurpleLotus certified or recognised? +
Yes. Our researchers are listed in top security halls of fame including Microsoft and GitHub, and we follow OWASP and CREST standards throughout every engagement.
Do you support open source projects? +
Absolutely. SecureCI/CD is free for qualifying open source projects. We believe the open source ecosystem deserves first-class security tooling — reach out with your project details.
Where does the Live Threat Feed data come from? +
Directly from the GitHub Advisory Database's public API, refreshed daily by an automated job. It's the same free, open data source that powers Dependabot — no paid data feed, no LLM-generated summaries.

Security that ships
with your code.
