The email security mistakes UAE businesses make most are relying only on built-in filters, weak sign-in, half-finished DMARC, yearly training, and no payment checks. Each one can be fixed in weeks, not months. This guide explains all five and gives you a simple checklist. Most fixes cost little, and a managed service can cover the rest.
Introduction
Email is still the front door for attackers. The UAE Cyber Security Council says more than 75% of cyber breaches begin with phishing emails or fraudulent messages.
That is why the email security mistakes UAE businesses make can cost so much. Most are not technical failures. They are habits, settings, and process gaps that nobody has reviewed in a while.
We see the same five problems again and again in small and mid-sized companies. The good news is that none of them needs a big team or a big budget to fix.
Whether you run a ten-person office in Dubai or a growing firm in Abu Dhabi, the steps are the same. Read them in order, or jump to the one that worries you most.
What Are the Most Common Email Security Mistakes UAE Businesses Make?
The most common email security mistakes are relying only on built-in filters, using weak sign-in, leaving DMARC unfinished, training staff once a year, and skipping payment checks. Each one gives attackers an easy route into your inbox or your bank account.
Here is the short list:
- Relying only on Microsoft 365 or Google Workspace filters
- Using passwords and basic MFA for every mailbox
- Leaving DMARC at “monitor only”
- Treating staff training as a once-a-year task
- Having no payment-change check and no one watching alerts
Most of these mistakes feel small on their own. Together, they leave several open doors.
Mistake 1: Why Isn’t Microsoft 365 or Google Workspace Protection Enough on Its Own?
uilt-in filters block most spam and known malware. They are a strong base. But attackers test their messages against the same filters, so new or targeted attacks can still reach the inbox. A dedicated email security layer catches what the platform misses.
Microsoft and Google block huge volumes of bad email every day. That is not the problem. The problem is the small share that gets through, because that share is built to look normal.
Criminals rent cheap phishing kits and use AI tools to write clean, personal messages. Newer tricks, like QR code phishing and fake invoices with no link at all, can slip past native filters.
A dedicated layer adds checks the platform does not focus on. These include impersonation detection, attachment sandboxing, and scanning of mailbox behaviour. We explain the biggest gaps in our guide to the email threats Microsoft 365 and Google Workspace won’t catch.
The fix: keep your built-in protection switched on, then add a specialist layer on top. Our advanced email security solutions in Dubai do exactly this for Microsoft 365 and Google Workspace.
Mistake 2: Is a Password and Basic MFA Still Enough for Business Email?
No. Passwords get reused and stolen, and basic MFA can be bypassed. Attackers now copy the session token after a user completes MFA. Phishing-resistant sign-in, such as passkeys or hardware keys, is much safer, especially for admins, finance staff, and shared mailboxes.
Many small teams still rely on a password and a text message code. Passwords get reused across sites, so one leak can open many accounts.
Basic MFA helps, but it is not perfect. In adversary-in-the-middle attacks, a fake login page passes everything to the real service. The user completes MFA as normal, and the attacker steals the session.
Shared mailboxes, like info@ and accounts@, are often the weakest spot. Many people use them, and they rarely get strong sign-in rules.
The fix: move admins and finance staff to passkeys or hardware keys first. Block old sign-in methods you do not use. Give shared mailboxes the same rules as personal ones.
Mistake 3: Is Your DMARC Record Really Protecting Your Domain?
Not if it is set to p=none. That setting only monitors fake emails and does not block them. A record at p=quarantine or p=reject tells receiving servers to stop spoofed messages that pretend to come from your domain.
Many companies publish a DMARC record and stop there. DMARC works with SPF and DKIM to check that an email claiming to come from your domain really did.
Many companies stop at this first step and never move to enforcement. The record exists, but spoofed emails keep getting through.
Why does it matter? Attackers can send emails that look like they come from your company, to your clients and suppliers. Your brand takes the blame, and your clients may lose money.
The fix: move in stages. Start with p=none and read the reports. Fix any real senders, such as your CRM or newsletter tool. Then move to p=quarantine, and finally p=reject. Our guide explains how SPF, DKIM, and DMARC work together.
Mistake 4: Why Does Once-a-Year Staff Training Not Work?
Many companies run one awareness session a year and call it done. Then a new hire joins, a new trick appears, and the lessons fade.
Attack styles change fast. AI tools now write messages with no spelling mistakes, so the old advice to look for typos is no longer enough. Our guide on AI phishing attacks in the UAE shows how convincing these emails have become.
Training also fails when reporting is hard. The UAE Cyber Security Council stresses that quick reporting helps response teams study a threat and act early. If staff do not know where to send a suspicious email, they will often delete it, or click it.
The fix: keep training short and frequent. Run small phishing tests each quarter. Add a one-click report button, and thank people who use it. Add simple rules, such as never signing in to a work account by scanning a QR code from an email.
Mistake 5: What Happens When No One Checks Payment Changes or Watches Alerts?
This mistake costs the most money. Business email compromise, or BEC, often has no link and no attachment. A message simply says the bank details have changed.
Fraudsters use this method because it works. One convincing request can lead a busy accounts team to send real money to the wrong account, and the money is hard to recover once the transfer clears.
Two gaps make it worse. First, there is no rule for checking payment changes. Second, security alerts fire, but nobody reads them at 2 a.m.
The fix: make a payment rule that never bends. Confirm every bank detail change by calling a known number. Require a second approver for new payees. Then make sure someone watches alerts all day, every day. Our Cybersecurity as a Service with a 24/7 SOC gives smaller teams that coverage without hiring an in-house team.
How Can a UAE Business Fix These Email Security Gaps This Month?
You can close most of these gaps in four to six weeks. Work through this order:
- Review sign-in. Move admins and finance staff to passkeys or hardware keys.
- Check your DMARC. Confirm your record exists, then plan the move to enforcement.
- Add a payment rule. Confirm every bank detail change by phone.
- Reset your training. Move to short, frequent sessions with a simple report button.
- Add a specialist layer and monitoring. Cover what built-in tools miss, and have experts watch alerts.

FAQ
What is the biggest email security mistake businesses make?
Relying only on built-in filters and basic passwords. Together they leave gaps for targeted phishing, token theft, and fake invoices. Layered protection works better: strong sign-in, a dedicated email security layer, trained staff, and clear payment checks.
Are small businesses in the UAE really targeted by phishing emails?
Yes. Phishing is cheap to send in bulk, so attackers aim at businesses of every size. The UAE Cyber Security Council reports that more than 75% of breaches begin with phishing emails. Smaller firms often have fewer checks in place.
What is the difference between DMARC p=none and p=reject?
The p=none setting only monitors and reports emails that fail checks. It blocks nothing. The p=reject setting tells receiving servers to refuse emails that fail DMARC, which stops most domain spoofing. The p=quarantine setting sits between them and sends failures to spam.
How often should staff do email security training?
Short sessions several times a year work better than one long yearly session. A good starting point is a quarterly phishing test and a quick refresher for every new hire. Making reporting easy matters just as much as how often you train.
How can I check my company’s email security?
Start by checking your SPF, DKIM, and DMARC records and your sign-in settings. Then review how your team approves payment changes. A free consultation with Cyber Security Solutions can show the gaps in your email setup quickly.
