Expert guidance on protecting your business from modern cyber threats — EDR, MFA, ransomware response, compliance, and security architecture.
Adding one include can push an SPF record past ten DNS lookups, and RFC 7208 requires receivers to return permerror. The record still looks valid to the eye and to many checkers, the failure moves between senders, and under a DMARC policy of reject the message rides entirely on DKIM.
Most domains publish p=none, which detects spoofing but blocks none of it. This walks the staged path to enforcement: what the removed pct tag actually did, why aligned DKIM is what saves forwarded mail, and a readiness test to run before you change the record.
You turned DMARC on and the zipped XML started arriving daily. This walks the report structure field by field, shows how to tell a real spoof from a broken SaaS sender or a forwarder that kept DKIM, and explains why zero failures is a narrower claim than it looks.
The technical answers came from your IT provider. The signature is yours. And the harder problem is not the application at all — it is proving the control stayed true all year.
MFA is on Microsoft 365 and the VPN, but not the backup service account or the break-glass admin. Is "yes" a lie? A walk through the real questions and the evidence each answer requires.
Your copier holds a directory bind account, an address book, and a disk full of scans — and no agent patches it. Here is how to build scanning with no standing domain credentials.
Because they arrange financing, auto dealers are "financial institutions" under the FTC Safeguards Rule. Here is what that requires, and how to comply without slowing the sales floor.
Modern ransomware crews hunt backups first and encrypt second. Immutable backups — copies that cannot be altered or deleted, even by an admin — are the control that keeps recovery on the table.
They get used interchangeably, but they answer different questions and cost very different amounts. Here is how to tell which one your business actually needs.
What DLP actually does, where it fits for a small or midsize business, and how to roll it out without drowning your team in false positives.
For growing businesses, hiring a CISO is a six-figure decision. A vCISO delivers similar coverage at a fraction of the cost — if fit is right.

A working AI acceptable use policy needs to cover sanctioned tools, data handling, review obligations, and consequences. Here's a practical template.
The five threats every business should plan defenses against in 2026: AI phishing, ransomware, supply chain, credential stuffing, and insiders.
AI-augmented attacks are real but specific. Here's where AI changes the threat model, where it doesn't, and the defensive shifts that matter.
Full zero trust is enterprise scope. Here's how SMBs apply zero trust principles selectively for most of the security benefit.
Modern phishing has eliminated the linguistic red flags. The defensive strategy has shifted from detection training to process verification.
What to do in the first 24 hours after a ransomware attack: isolation, insurance, the pay-or-restore decision, and the recovery sequence.
EDR replaced traditional antivirus as the business endpoint standard. Here's what it does, how it differs, and when to layer MDR on top.
MFA isn't optional anymore. Here's the 2026 view of MFA strength tiers, what accounts need it, and the common implementation mistakes.
Most breaches exploit known vulnerabilities where the patch existed. Here's the patching discipline that actually closes that gap.
Plans built before incidents make incidents survivable. Here's the IR plan that actually works during a real event, not just on paper.
Dark web monitoring catches compromised credentials early. Here's what it actually finds, what it doesn't, and how to act on alerts.
IoT devices weren't designed with security in mind. Here's the architectural approach that defends them: segmentation, monitoring, and discipline.
Password managers solve credential reuse cheaply. Here's how to deploy them at business scale, including the rollout mistakes to avoid.
Building real security culture is more consequential than any single tool. Here's what actually creates it — and what destroys it.
Securing business email requires layered defenses: SPF/DKIM/DMARC, anti-phishing, MFA, BEC detection. Here's the configuration audit.
Cloud security isn't more or less than on-prem — it's different. Here are the high-leverage controls SMBs should focus on.
Most breaches follow the same five stages. Understanding that pattern shows where defensive investments deliver the highest return.
MDR delivers SOC-quality threat detection without building one internally. Here's what it includes and how to evaluate providers.
Cyber insurance has become an underwriter. Here's what carriers require for coverage in 2026 and how to improve insurability.
DNS-layer security catches threats at the moment of lookup, before connections happen. Here's why it's the most underrated security control.
Admin credentials are the highest-value attack target. Here's how PAM works at SMB scale without enterprise tooling complexity.
How to build a security budget without a CISO: the framework, the priority sequence, and how to make the case to leadership.
NIST publishes the standard, CIS makes it actionable, CMMC formalizes it for defense contractors. Here's how they fit together.
Modern breaches come through vendors. Here's the risk-tiered vendor management practice that limits third-party exposure.
Post-quantum cryptography is coming, but not panic-now. Here's the realistic preparation timeline and what SMBs should actually do.
MSP and MSSP look similar in marketing but deliver different things. Here's the distinction and how to pick the right model.
