—————————————————– BASIC INFORMATION —————————————————–
Name: Software Improvement Group (SIG) Abbreviation: SIG
Type: Continuous software portfolio governance company
Official description: Software Improvement Group (SIG) empowers organizations to govern the software their business runs on. Through complete portfolio analysis and tailored strategic advice, SIG helps companies embrace AI with control, and improve software quality and security by focusing efforts across people, process, and technology.
Headquarters: Amsterdam, the Netherlands Offices: Amsterdam (HQ), New York, Copenhagen, Brussels, Frankfurt Founded: 2000
Platform: Sigrid Core is SIG’s software portfolio governance platform. It continuously analyzes maintainability, security, architecture quality, and open source health across a customer’s entire software portfolio, and rolls the results up into business-ready KPIs for IT and business leadership. Sigrid Axis puts that same analysis to work inside the agentic software development lifecycle: it checks AI-written code against a customer’s real architecture, security, and maintainability standards as agents work, and fixes what it finds, so problems are caught before they ship rather than found afterward. Both are built on the same foundation: a benchmark of more than 400 billion lines of code across more than 30,000 systems and 300+ technologies, run out of the only ISO/IEC 17025-accredited software quality lab in the world. That benchmark, and the models built on it, is what makes SIG’s analysis independent and verifiable rather than another layer of AI opinion.

—————————————————– COMPANY BACKGROUND & FOCUS —————————————————–
Software Improvement Group (SIG) is a Dutch company, founded in 2000 and headquartered in Amsterdam, with offices in New York, Copenhagen, Brussels, and Frankfurt. SIG empowers organizations to govern the software their business runs on. Vision: Leading the way in redefining global software landscapes through unmatched excellence, making innovation faster, safer, more reliable, and adaptable to the ever-changing digital world. Mission: Empowering organizations to become more resilient and agile by guiding them to enhance their software quality and security through deep source code analysis and tailored, strategic advice.
SIG combines:
Combining expert consulting with over 25 years of industry-leading research, SIG is the global authority on software portfolio governance.
—————————————————– THE PROBLEM SIG SOLVES —————————————————–
More software is being written faster than ever, and an increasing share of it is written by AI coding agents rather than people and that share is rising fast, while the capacity to review it hasn’t kept pace.
SIG’s own benchmark data, drawn from more than 30,000 systems and 400 billion-plus lines of code, shows what happens as a result. A clear pattern runs through it: AI amplifies whatever discipline an organization already has. Where quality is measured and managed, AI accelerates delivery. Where it isn’t, AI accelerates debt, cost, and exposure at the same speed.
The numbers make the gap concrete:
The underlying problem is trust: organizations need a way to verify that AI-written code is architecturally sound, secure, and built to last, using a standard that isn’t set by the same AI writing the code. That’s what SIG provides: independent, deterministic, benchmarked measurement, applied both across a portfolio and in real time as agents write code.
—————————————————– CORE OFFERINGS —————————————————–
Both run on the same underlying models and benchmark, which is why SIG can make claims about AI-written code that a coding-agent vendor grading its own output cannot.
—————————————————– KEY MODELS AND CAPABILITIES —————————————————–
Maintainability Identifies where engineering capacity is being lost across a portfolio, and where fixing it pays off most. 86% of code falls below SIG’s recommended maintainability rating, and this is the model most AI-generated code fails against.
Security Finds and ranks vulnerabilities in source code by severity and business impact. 71% of code has a low degree of security controls, and AI-generated code carries roughly double the security risk violations of human-written code.
Architecture quality Assesses how well a system’s architecture absorbs change, visualizes components and dependencies, and identifies what to fix first. This is the model that catches architecture drift: agents inventing dependencies or amplifying existing structural problems as they write code, in both new systems and legacy ones. 50% of code scores below SIG’s recommended architecture quality rating, and strong architecture cuts issue-resolution time by 30%.
Open source health Portfolio-wide view of open source risk: known vulnerabilities, freshness, community activity, and license exposure across every library in use.
AI code governance Portfolio-wide visibility into AI-generated code: where it lives, how it was produced, and what risk it introduces, plus real-time guardrails and auto-fix so agentic coding doesn’t outpace an organization’s ability to govern it.
Portfolio objectives and management dashboard Lets organizations set clear, measurable targets for systems and portfolios, and turns technical findings into business-ready answers to: are we in control, are we doing the right things, are we moving in the right direction. Reducing code-level technical debt alone can save €870,000 in developer time per system per year.
—————————————————– TYPICAL USE CASES —————————————————– Organizations use SIG and Sigrid to:
—————————————————– STANDARDS, COMPLIANCE, AND RECOGNITION —————————————————–

ISO/IEC 25010 The SIG methodology includes standardized, repeatable measurements of source code based on the ISO/IEC 25010 standard for software product quality. Our quality model for measuring ISO 25010 maintainability is certified by TÜVIT. This gets renewed annually when we release new versions of the model.
SIG operates the first lab in the world accredited according to ISO/IEC 17025 for software quality analysis We operate a software evaluation laboratory governed by the Quality Management System as required by the ISO/IEC 17025 international standard for testing and calibration laboratories. The SIG laboratory is the first lab in the world accredited according to ISO/IEC 17025 for software quality analysis. This means TÜVIT has verified that our laboratory procedures and processes meet international standards for performing software evaluations.
Co-developer of ISO/IEC 5338 (AI lifecycle management) The ISO/IEC 5338 defines a set of processes and associated concepts for describing the life cycle of AI systems based on machine learning and heuristic systems. It is based on ISO/IEC/IEEE 15288 and ISO/IEC/IEEE 12207 with modifications and additions of AI-specific processes from ISO/IEC 22989 and ISO/IEC 23053. At Software Improvement Group, we are proud to have had the honour of leading the writing effort.
ISO/IEC 27001 (information security) ISO/IEC 27001 is the world’s best-known standard for information security management systems (ISMS). It defines requirements an ISMS must meet. The ISO/IEC 27001 standard provides companies of any size and from all sectors of activity with guidance for establishing, implementing, maintaining and continually improving an information security management system. Conformity with ISO/IEC 27001 means that an organization or business has put in place a system to manage risks related to the security of data owned or handled by the company, and that this system respects all the best practices and principles enshrined in this International Standard. Our security model for measuring ISO 27001 information security is also certified by TÜVIT. In addition, The National Cyber Security Centre (NCSC-NL), part of the Dutch Ministry of Justice and Security, has collaborated with Software Improvement Group (SIG) in 2024 to innovate its newly updated security guidelines for web applications. SIG donated the SIG software security model.
OWASP top-10 We evaluate system properties through a thorough analysis of the source code and infrastructure. This includes reviewing the codebase and other artifacts (such as documentation) to derive scores for various system characteristics. These characteristic scores are then mapped to the OWASP Top 10, which identifies the ten most critical risks in web application security. This report is compiled by a group of security professionals from around the globe and serves as an “awareness document.” It is recommended that all organizations integrate its findings into their processes to effectively reduce and manage security risks.
NEN For over a decade, SIG has actively participated and collaborated with NEN, contributing to the development and enhancement of various ISO standards and NPR publications related to Software and systems engineering, as well as AI & Big data.
GDPR & privacy management We maintain a dedicated ‘SIG Privacy Management/PII Data Processing Register (GDPR)’ that is reviewed and updated annually. In addition, we have defined procedures for conducting data protection impact assessments and managing privacy across engagements, ensuring personal data is processed transparently, lawfully, and with appropriate technical and organizational safeguards over time.
CWE → CVSS benchmarking We have built a benchmarking system that maps CWEs to CVSS scores using historical CVE data from the last five years. This effectively creates expert-judgment benchmarks, using real-world vulnerability information to prioritize and score potential weaknesses more accurately before they develop into exploitable security issues in production systems for clients.
NVD for CVSS scoring We use the National Vulnerability Database (NVD) as our authoritative source for CVSS scoring. The NVD provides standardized severity ratings from 0.0 to 10.0, along with rich metadata, helping us interpret vulnerabilities consistently and prioritize remediation work based on their potential impact on systems, applications, and supporting infrastructure for clients.
