STLUR

Continuous Security as a Service

STLUR runs your security desk, automatically, every month.

Continuous external assessments, prioritized findings, and decision-ready reporting. A security function — without the hire, without the overhead.

Aligned with SOC 2, ISO 27001, and OWASP, STLUR delivers monthly evidence built for engineers, executives, and auditors alike.

The Cost of Inaction

By the time it makes the news, it is already a financial event.

What happened to companies that deprioritized security. Every case below is a documented fact, not a cautionary tale.

Real-World Breach Cases

Code Spaces2014

Continuity

Stopped in 12h

12 hours from breach to bankruptcy

The root AWS account had no MFA, so stolen credentials alone gave full access. After ransom was refused, the attacker deleted every instance, bucket, and snapshot. The company had no path to recovery and shut down the same day. Skipping MFA at cloud setup erased the entire business.

Continuity

Stopped in 12h

Cause

No MFA on the root AWS account

Yahoo! (US)2013–2014

Accounts impacted

3B+

Weak hashing erased ~$350M in acquisition value

Two breaches in 2013 and 2014 went undisclosed until 2016. MD5-hashed passwords were trivially crackable, enabling continuous exploitation. All 3 billion accounts were ultimately affected. Yahoo's Verizon acquisition price was cut by $350M over the hidden incident.

Accounts impacted

3B+

Cause

Legacy MD5 hashing and delayed disclosure

British Airways2018

Customers affected

~500K

22 lines of code that shook a global brand

Magecart inserted 22 lines of skimmer code into a third-party JavaScript loaded on the checkout page. Every card detail entered was forwarded to attackers in real time for nearly two weeks. About 500K customers were affected and the initial GDPR fine proposal reached £183M.

Customers affected

~500K

Cause

Third-party JavaScript injection (Magecart)

Equifax2017

Records exposed

148M

An unpatched vulnerability exposed 148M people

A critical Apache Struts patch (CVE-2017-5638) sat unapplied for two months. Attackers exploited it, remained undetected for 76 days, and exfiltrated 148M records including SSNs and birth dates. Total settlement and fine costs exceeded $575M. The CEO and CIO resigned.

Records exposed

148M

Cause

CVE-2017-5638 left unpatched for 2 months

Target2013

Cards stolen

40M

An HVAC vendor's credentials breached 40M cards

Credentials stolen from an HVAC vendor provided a foothold inside Target's corporate network. Poor network segmentation let malware spread to 4,000+ POS terminals during Christmas season. 40M payment cards and 70M personal records were stolen, triggering CEO and CIO resignations.

Cards stolen

40M

Cause

Vendor network not isolated from POS systems

SolarWinds2020

Orgs compromised

18,000+

A trusted software update became a nation-state weapon

Attackers inserted the SUNBURST backdoor into a legitimate monitoring software update. Over 18,000 organizations installed it — including the US Treasury and State Departments. The intrusion went undetected for ~9 months and redefined supply-chain attacks as a top-tier threat.

Orgs compromised

18,000+

Cause

Build system compromise and malicious code injection

Change Healthcare2024

Total loss

~$3B+

One missing MFA setting halted US healthcare for weeks

One internal account lacked MFA on a critical system. A single stolen password was enough for ransomware operators to access the core. US pharmacies and hospitals stopped processing prescriptions and payments for weeks. Total losses to UnitedHealth Group exceeded $3B.

Total loss

~$3B+

Cause

MFA missing on a critical access account

CrowdStrike2024

Machines crashed

8.5M

A security vendor's own update caused history's largest IT outage

A faulty content update — not malware — crashed 8.5M Windows machines globally. Airports, banks, hospitals, and broadcasters halted simultaneously. Fortune 500 firms alone lost $5.4B+. A trusted security vendor proved a single bad update can outscale any cyberattack.

Machines crashed

8.5M

Cause

Unvetted content update pushed to production

Bybit2025

Stolen

~$1.4B

Phishing seized the keys behind a multi-sig wallet

Phishing and access exploitation let attackers seize the signing environment of a multi-signature wallet. The multi-sig protocol itself was intact, but the human layer managing the keys was compromised. ~$1.4B in Ethereum was stolen — the largest single crypto theft in history.

Stolen

~$1.4B

Cause

Phishing compromise of multi-sig key managers

Coverage Architecture

A single overlooked misconfiguration can compromise your entire system.

Attackers don't attack your strongest defenses; they look for abandoned subdomains, unmonitored APIs, and minor cloud misconfigurations. STLUR dissects your business into four distinct layers—from the public surface down to authenticated regions—and continuously hunts for vulnerabilities from a hacker's perspective.

Public Surface

Everything an attacker sees first

Domains, SSL/TLS, exposed ports, leaked metadata. The surface that defines your initial risk posture.

Configuration

Misconfigurations are the most ignored vulnerability

Security headers, TLS settings, public storage, dependency drift — checked continuously, not annually.

API & Endpoints

Hidden doors live in your traffic

Undocumented endpoints, leaky responses, weak input validation. The risks unique to your application boundary.

Authenticated

The real impact lives behind login

On Enterprise, with verified ownership and consent, STLUR runs dynamic testing (DAST) inside authenticated regions.

Enterprise DAST Architecture

Deep, authenticated audits, architected for absolute security.

Safely and comprehensively diagnose vulnerabilities deep within your system, beyond the login screen. Through secure session handoffs via our dedicated browser extension and isolated scanning environments, we completely eliminate the risk of production impact and data leakage.

STL 01

Secure Integration via Extension

Use the STLUR Chrome extension to securely synchronize auth credentials or session tokens from your local environment. No plaintext passwords stored on our servers.

STL 02

Encrypted Session Vault

Received sessions are heavily encrypted and managed strictly within a secure vault. They are loaded into memory only during the scan to maintain safe access.

STL 03

State-Aware Dynamic Scanning

Not just a crawler, but an engine that understands application state. We deeply and accurately trace post-login processes involving complex transitions and API calls.

STL 04

Fully Isolated Audit Environment

Scans execute on isolated, ephemeral microVMs for each customer. Physical data boundaries ensure that your audit data never leaks to other environments.

Reports for Decision-Making

One assessment. Three audiences. Three optimized outputs.

Vulnerability reports change meaning depending on who reads them. STLUR generates the right shape for engineering, leadership, and audit — from the same evidence.

For Engineer

Reproducible. Fixable. Verifiable.

• Administrative privilege escalation

• Data exfiltration through DOM manipulation

• Cross-origin request forgery (CSRF)

SearchController::process()

REMEDIATION STRATEGY

Immediate Fix (Priority 1)

// PHP Implementation

FILTER_SANITIZE_SPECIAL_CHARS);

echo htmlspecialchars($input, ENT_QUOTES, 'UTF-8');

Long-term Security Measures

1. Content Security Policy (CSP) implementation

2. Input validation whitelist approach

3. Output encoding for all user data

4. Regular security code review process

Governance & Evidence

Monthly third-party audit records, the only proof of trustworthiness.

When an incident lands, the question is what you did before it. STLUR's monthly reports become defensible evidence — across audit, vendor risk, and corporate due diligence.

Supporting evidence for SOC 2 / ISO 27001
External assessment records, scope, and remediation status — packaged for auditor reference.
Vendor reviews and security questionnaires
Concrete monthly artifacts to back up your security posture, not adjectives.
Cyber due diligence in M&A and IPO
Removes 'unmanaged web security' as a value-discount lever during diligence.
