Expensify launched an MCP server on June 8, 2026, letting Claude, ChatGPT, and Cursor query live expense data via OAuth 2.1.

Only 38% of small businesses carry cyber insurance, 44% of insured ones are underinsured, and nearly half of claims are denied or closed without payment. A guide to the ransomware sublimits, social engineering caps, and security-control requirements that determine whether a policy actually pays.
Small business cyber insurance runs roughly $400–$1,600 a year for a $1 million limit, while the average breach recovery costs $120,000 and downtime $53,000 an hour. A guide to first-party vs. third-party coverage, 2026 premium drivers, and the social-engineering sublimits and MFA requirements that most often sink claims.
Generative AI made vendor impersonation cheap: 76% of organizations faced payments fraud in 2025, and AI-generated fakes now drive 70.8% of expense-report fraud. Here are the controls that still work — out-of-band verification, dual authorization, vendor-file hygiene, and auditable books.
The IRS's 2026 Dirty Dozen list flags a payroll-specific phishing wave: fake HR portal emails and direct-deposit change requests that reroute paychecks to scammers. The FBI's IC3 logged 24,768 business email compromise complaints totaling roughly $3.05 billion in 2025, with 86% of losses moving by wire or ACH — the same rails payroll runs on. Here are the three warning signs (urgency, unusual requests, process changes), five process controls that close the email-only loophole, and the first-72-hours response if a paycheck has already been diverted.
Missouri's HB 974, signed July 2, 2025 and effective January 1, 2026, applies the NAIC Insurance Data Security Model Law to nearly every insurance licensee in the state — requiring a written security program, annual risk assessments, an incident response plan, vendor oversight, and breach notification to regulators within four business days.

Here's what changed from the 2009 guidance, how the CSF 2.0 six functions translate to a solo operation, and a 30-minute checklist to act on today.
A 2026 TIGTA audit found 1,375 unauthorized entries into restricted taxpayer-document areas and critical vulnerabilities left unpatched an average of 223 days at IRS scanning contractors. Here is what the watchdog found, how the IRS responded, and the concrete steps — IP PIN enrollment, early filing, e-filing — that reduce your exposure.
73% of accounting firms now use AI tools but only 37% have any formal AI training, and staff pasting client data into consumer chatbots can trigger data breach notification duties under the AICPA's Confidential Client Information Rule — here is what a usable two-page AI policy for a small CPA firm actually covers.
A code-audit firm selling fixed-scope static audits, hourly remediation, and resold SAST subscriptions runs three ASC 606 revenue-recognition rules under one roof — point-in-time, as-performed, and ratable. This guide covers the chart of accounts to separate them, the principal-vs-agent test for reseller margin, and a worked example posting one client engagement across unearned revenue, unbilled receivables, and subscription margin.
Chase rolled out passkey login and a Trusted Contact Person feature in early 2026 to counter AI voice-cloning fraud, which costs small businesses $30,000 to $400,000 per incident on average.
