Stay informed on the latest IT trends." canonical: https://efros.com/blog/ --- - [Home](https://efros.com/) - /Blog # IT & Cybersecurity Insights Technical analysis on cybersecurity, cloud architecture, IT operations, and compliance. Written by the engineers doing the work, not a marketing team. By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · June 19, 2026 ## What you'll find here This is where we publish the longer-form analysis that doesn't fit on a service page. Topics cluster around what we operate in daily: cybersecurity threats and defense patterns, cloud architecture and migration, managed IT operations, compliance frameworks, and AI governance for clients running generative AI in regulated contexts. Every article is written by someone on the EFROS team with direct operational experience in the topic. No marketing ghostwriting, no AI-templated content, no generic industry best practices you've read on ten other blogs. Our analysis cites primary sources when it can: [NIST](https://www.nist.gov/cyberframework), [CISA](https://www.cisa.gov/), [MITRE ATT&CK](https://attack.mitre.org/), the [Verizon DBIR](https://www.verizon.com/business/resources/reports/dbir/), and the [IBM Cost of a Data Breach Report](https://www.ibm.com/reports/data-breach). ## How we pick topics Our topic pipeline comes from client work. When we see the same question surface across multiple engagements, that tells us the broader market is underserved on the topic. [Current threat analysis](https://efros.com/blog/top-cybersecurity-threats-2026/) exists because every CISO we work with asked variations of the same question last quarter. [MDR vs EDR vs XDR](https://efros.com/blog/mdr-vs-edr-vs-xdr-complete-comparison-2026/) exists because the acronym confusion in security buying costs real organizations real money. For platform-level benchmarking we cross-reference [MITRE ATT&CK Evaluations](https://evals.mitre.org/). [CMMC 2.0 readiness](https://efros.com/blog/cmmc-2-defense-subcontractors-compliance-roadmap/) exists because primes are flowing the requirement down to subcontractors with compressed deadlines and most subcontractors need the technical map, not another compliance lawyer's summary. ## Who writes for us Everything you'll read here is authored by Stefan Efros, CEO & Founder of EFROS, including the SOC, MDR, and incident-response material. Every article carries a named author and a named reviewer. We don't publish under a generic "EFROS team" byline, because that's a signal the author doesn't want to be accountable for what they wrote. ## Browse by category [AI Governance](https://efros.com/blog/category/ai-governance/) [Cybersecurity](https://efros.com/blog/category/cybersecurity/) [Compliance](https://efros.com/blog/category/compliance/) [Cloud](https://efros.com/blog/category/cloud/) [IT Management](https://efros.com/blog/category/it-management/) ## Recent articles Cybersecurity 12 min read SE Stefan Efros · Apr 22, 2026 ## Top Cybersecurity Threats Businesses Face in 2026 AI-powered phishing, triple-extortion ransomware, supply chain compromise, and cloud misconfigurations.
