Assessment and Baseline (2-3 weeks)

• Inventory code repositories (GitHub, Azure DevOps, GitLab, Bitbucket)
• Assess current security posture (existing tools, vulnerability backlog, remediation velocity)
• Identify critical applications and high-risk code
• Establish baseline metrics (findings per repo, time to remediate, developer engagement)
• Define success criteria (target backlog reduction, remediation SLAs, deployment velocity)

GitHub Advanced Security Deployment (3-4 weeks)

• Enable GHAS for pilot repositories (2-3 critical applications)
• Configure CodeQL scanning (choose language support, custom queries if needed)
• Enable secret scanning with partner notifications
• Activate Dependabot security updates
• Set up security policies (branch protection, required reviews, status checks)
• Train developers on GHAS workflows (PR feedback, fixing vulnerabilities, using Copilot suggestions)

Defender for Cloud Integration (4-6 weeks)

• Deploy Defender for Cloud across Azure, AWS, GCP workloads
• Enable Defender for DevOps (connects to GitHub, Azure DevOps)
• Configure runtime monitoring for production applications
• Set up cloud security posture management (CSPM)
• Enable attack path analysis and cloud workload protection
• Configure integration with GitHub (code-to-cloud correlation)

Intelligent Prioritization Setup (2-3 weeks)

• Define prioritization rules (production exposure, data sensitivity, privilege level)
• Configure automated issue creation for high-priority findings
• Set up notification workflows (Slack, Teams, email based on severity)
• Create security dashboard for leadership visibility
• Establish SLAs per severity level (Critical: 48 hours, High: 7 days, etc.)

AI-Powered Remediation Enablement (4-6 weeks)

• Deploy GitHub Copilot enterprise-wide (or to developer pilot group)
• Enable Copilot Autofix for security vulnerabilities
• Train developers on using Copilot for security remediation
• Pilot agentic workflows (AI-generated fix PRs for low-risk vulnerabilities)
• Measure adoption and effectiveness (fix acceptance rate, time savings)

Scale and Optimize (Ongoing)

• Expand GHAS to all repositories in phased rollout
• Refine prioritization rules based on real-world effectiveness
• Monitor metrics weekly (backlog trends, remediation velocity, deployment impact)
• Continuously improve Copilot training (feedback on fix suggestions)
• Expand agentic automation to more vulnerability classes
• Measure business impact (security incidents prevented, audit efficiency, developer productivity)

🇸🇪 Technspire Perspective: Swedish E-Commerce Platform's DevSecOps Journey

A Swedish e-commerce platform (520 developers, 8.5M customers, €420M annual revenue) faced a security crisis: PCI-DSS audit identified 230 vulnerabilities in payment processing code. Auditors gave 90 days to remediate or lose certification (and ability to process credit cards).

The challenge: 230 vulnerabilities × 3-5 days per fix = 690-1,150 developer days. With 90 days to fix, they'd need 8-13 full-time developers doing nothing but remediation. Impossible while maintaining business operations.

The Technspire solution: Emergency DevSecOps implementation:

Week 1-2: Deployed GHAS + Defender for payment processing repositories (12 repos, 450K lines of code)
Week 2-3: Runtime context analysis—Defender mapped which vulnerabilities were in active payment flows vs. deprecated code
Week 3-4: Intelligent prioritization reduced 230 findings to 87 critical issues (others were false positives or unexploitable)
Week 4-12: AI-powered remediation—GitHub Copilot Autofix generated secure code for 73 of 87 issues. Developers reviewed and refined, significantly faster than manual rewrites

Results:

Remediation completed: 87 critical vulnerabilities fixed in 82 days (8 days ahead of deadline)
Developer effort: 180 developer days (vs. 690-1,150 estimated)—74-84% time savings from Copilot assistance
PCI-DSS certification: Renewed without conditions. Auditors praised their DevSecOps maturity
Ongoing impact: New vulnerabilities introduced: -67% (Copilot suggests secure patterns). Security debt: eliminated and stays at zero (continuous scanning prevents accumulation). Deployment frequency: unchanged (security no longer blocks releases)

Business outcome: Avoided losing €420M revenue stream. Security became enabler of business growth, not blocker. Developer satisfaction increased—they see security as partner, not adversary.

Why This Matters for Swedish Organizations

Sweden's organizations are leaders in software development velocity—but speed without security is reckless. GHAS + Defender addresses critical Swedish concerns:

GDPR compliance: Automated secret scanning prevents accidental credential exposure. Dependency scanning ensures third-party packages meet privacy standards. Full audit trails for regulatory inquiries.
NIS2 critical infrastructure: Energy, healthcare, finance, transport—GHAS + Defender provide security controls and incident response capabilities required by NIS2.
EU AI Act readiness: Code-level security for AI systems. Traceability from AI model to underlying code vulnerabilities.
Resource efficiency: Smaller Swedish security teams can manage large codebases when AI handles triage and remediation.
Developer productivity: Security becomes accelerator, not blocker. Copilot suggestions are often better than manual fixes.
Competitive advantage: Ship features faster with confidence. Security maturity wins enterprise customers.

Key Takeaways from BRK112

✓ GitHub Advanced Security + Defender for Cloud integration connects code to runtime context for intelligent prioritization
✓ Only 2-5% of vulnerabilities are actually exploitable in production—runtime intelligence identifies them
✓ AI-powered remediation with GitHub Copilot reduces fix time from days to hours with secure code suggestions
✓ Agentic workflows enable autonomous vulnerability fixes—developers review instead of rewrite
✓ Alert fatigue eliminated through multi-layered noise reduction (85-95% fewer irrelevant alerts)
✓ Unified tooling: Developers work in GitHub, security teams see everything in Defender—no context switching
✓ Security accelerates development: Organizations report 40-60% faster deployment velocity after implementation
✓ Organizations report 74-84% time savings on vulnerability remediation with Copilot assistance

The DevSecOps transformation is here. GitHub Advanced Security + Microsoft Defender for Cloud + AI-powered remediation create a secure-by-default development ecosystem where security enhances velocity instead of blocking it. For Swedish organizations balancing innovation speed with regulatory compliance, this integrated approach is the path to sustainable, secure software development. The future isn't choosing between speed and security—it's achieving both through intelligent automation.
