A contractor finishes a project in March—does their guest account still have access to your SharePoint files in September? 📁🚪

It's easy to invite clients, vendors, and freelancers into Microsoft Teams or SharePoint for a quick project. But without an offboarding review, temporary access quietly turns into permanent exposure.

With Microsoft shifting all external sharing in SharePoint and OneDrive to Microsoft Entra B2B, active guest account management is more critical than ever.

Under PIPEDA, Canadian organizations remain legally accountable for personal data shared with third parties. Setting guardrails like guest access expiration, domain restrictions, and regular sharing audits ensures collaboration stays secure without leaving the door open.

Is an old "Anyone with the link" shortcut leaving your confidential files exposed? 🔗📁

It happens every day: an employee needs to send a package quickly, picks "Anyone with the link," and sends it off. But unless that link is set to expire, it stays active long after the project ends—granting access to anyone who obtains the URL.

During one M365 audit, an IT provider uncovered over 35,000 active anonymous links in a single tenant!

Under PIPEDA, an exposed link leaking sensitive personal data can trigger mandatory reporting obligations to the Privacy Commissioner of Canada.

The good news? A quick M365 sharing audit lets you set safer defaults—like "Specific People"—without slowing down daily collaboration.

Is your "Contact Us" form inviting malware directly into your inbox? 📩⚠️

Your website contact form is designed to invite complete strangers to upload files—like resumes, quotes, or damaged product photos. But because file upload controls go unmonitored for years, hackers routinely exploit them to infiltrate servers and send weaponized attachments straight to staff inboxes.

In fact, a major file-upload flaw in a popular WordPress form plugin made headlines when it allowed unauthenticated file uploads to servers.

Good contact form security doesn't mean turning off file uploads—it means enforcing strict file-type restrictions, automatic file renaming, off-site storage, and pre-delivery antivirus scanning.

An employee resigns on Friday, the team says goodbye, and by Monday everyone has moved on. But are their email, VPN, and cloud folder accesses still active?

Unrevoked access is one of the quietest security risks small businesses face—because everything looks completely normal until it isn't. Stolen and abused credentials remain one of the top ways attackers break into company networks.

Disabling access as soon as an employee leaves isn't just an HR process; it's a critical security event:
- Cut core access immediately (Email, VPN, Single Sign-On) during their last working hour.
- Audit standalone apps like password managers, accounting software, and industry tools that don't use SSO.
- Don't forget shared passwords (social media, team inboxes, vendor portals) that outlive individual employee accounts.

Protect your business data and eliminate lingering risks before the next departure.

A courier asks your receptionist to scan a QR code to confirm a delivery. A field technician scans a code on a piece of equipment to open a service manual. Neither feels risky—and that’s exactly why attackers are targeting them.

Welcome to Quishing (QR code phishing).

Because a QR code is just an image, malicious links hide right in plain sight. They bypass traditional email text-filters and directly target mobile devices operating outside corporate firewalls.

Front-desk and field teams are prime targets because scanning codes is part of their fast-paced, daily routine.

Here is how to protect your team without slowing them down:
- Build the "Pause-Verify-Report" habit: Ask if there's another way to get the info, or manually type the URL.
- Check the camera preview: Train staff to actually inspect the link destination before tapping it.
- Create a judgment-free reporting system: If someone accidentally scans a bad code, fast reporting prevents a minor slip from becoming a major incident.

Sharing is caring—except when it comes to your business login credentials. 🔑🚨

Whether it’s a social media account used by three staff members, a shared inbox with a password that hasn't changed in years, or a master "admin" account shared to avoid buying extra user seats, shared logins are an invisible compliance trap.

Many owners assume that migrating to a modern, passwordless workplace using biometrics or passkeys fixes this issue, but it doesn't—it just shifts the risk. Shared credentials are a people-and-process problem, not a technical one.

The real cost of shared accounts:
- Zero Accountability: When multiple people operate under a single identity, audit logs become completely meaningless during a security or data investigation.
- PIPEDA Compliance Liability: Under Canada's federal privacy law, businesses must protect data with appropriate access controls. If you cannot produce a reliable log of exactly who accessed personal client info and when, your business faces massive compliance vulnerability.
- Offboarding Nightmares: Revoking access for a single departing employee becomes a complex hurdle when changing the master login disrupts everyone else on the team.

The goal is to make your data access traceable, revocable, and defensible.

Think a strong password and multi-factor authentication make your business unhackable? Think again. 🌐🍪

Cybercriminals are increasingly skipping passwords altogether. Instead, they are launching session hijacking attacks using stolen browser cookies. In fact, security researchers captured a staggering 8.6 billion stolen session cookies from underground criminal networks in a single year!

How the attack works: A session cookie is a temporary digital pass your browser stores after you log into a platform (like Microsoft 365, Slack, or your accounting software) so you don't have to re-enter credentials on every page. If an attacker steals that active cookie via infostealer malware or compromised browser extensions, they can drop it into their own browser and walk straight into your active accounts—completely bypassing your passwords and MFA screens.

Protect your business data by implementing basic browser hygiene:
- Clear Weekly: Make clearing browser cookies a weekly baseline habit for business devices.
- Isolate Work Profiles: Use dedicated browser profiles specifically for work apps to minimize cookie accumulation.
- Automate Shared Desks: Configure public or shared office workstations to automatically clear cookies the moment the browser closes.

Treat your session cookies with the exact same care as a password.

That smart thermostat on the wall, the boardroom TV, or the office printer that scans straight to email—when was the last time any of them had a password change or a software update? 🖥️🔒

It’s easy to focus cybersecurity efforts entirely on laptops and servers, but everyday "Internet of Things" (IoT) devices are effectively small computers sitting on your network. Because they are often installed once and forgotten, cybercriminals view them as the ultimate "soft targets" to quietly break into a business network and access sensitive emails, files, or accounting data.

Securing your office doesn't require a massive IT overhaul. Running a simple, quarterly office IoT audit checklist—like changing default factory passwords and setting up network segmentation—closes the most common vulnerabilities before attackers can exploit them.

Think your business is 100% safe from phishing just because you have multi-factor authentication (MFA) turned on? Unfortunately, the threat landscape has evolved. 🛑⚠️

Modern cybercriminals now use "adversary-in-the-middle" phishing kits that trick users into entering their passwords and approving their MFA push notifications on a lookalike page. Within seconds, the attacker intercepts the session and logs directly into your company's email or cloud data.

To truly protect your team, you need to remove the password from the equation entirely. A structured passkey migration moves your business to cryptographic logins that are mathematically impossible for hackers to phish or replay. Best of all, it can be rolled out in simple phases without disrupting your team's daily workflow.

Is a "helpful" browser extension quietly leaking your data? 🔐🕵️

Most browser extensions feel like harmless shortcuts for grammar, summaries, or productivity. But in 2026, many of these "Shadow AI" tools have the power to read, capture, and transmit everything you do inside your browser tabs—including sensitive client portals and banking.

For Canadian businesses, this isn't just an IT glitch; it's a major PIPEDA compliance risk. Accountability doesn't disappear just because a tool is "just an extension."

Learn how to run a simple 5-minute security audit to identify unsanctioned extensions and close hidden data paths before they become a liability.
