- Prioritise supplier bank-change and marketplace login pretexts over retail spam thrills.

How we ranked
Ranking for online retailers and multi-channel brands in 2026 uses five filters: quality of BEC and invoice-fraud simulations; coverage of marketplace and ad-platform login lures; speed of auto-remediation for clickers in small lean teams; reporting founders and ops leads will actually open; and cost model that does not punish seasonal headcount spikes. Tools without realistic payment diversion templates cannot earn Buy.
The ranked list
1. Cyber Aware — the retail-ops Buy
Cyber Aware ships 100+ templates that include invoice and portal patterns, auto-enrols clickers into short lessons, and tracks risk with human risk reporting. Localisable sends fit brands with warehouse, CX and finance cohorts on different shifts. Multi-tenant mode also suits MSPs packaging awareness into retail client retainers. Verdict: Buy for most e-commerce teams under a few hundred seats in 2026.
2. KnowBe4 — the catalogue-depth Hold
Deep library and mature enterprise flows. Heavier for a 30-person D2C brand that needed something running this month. Verdict: Hold if you already have admin capacity permanently assigned.
3. Proofpoint / email-security bundles — the stack-tied pick
Strong when already paid as filter plus awareness. Weak as a standalone behaviour programme for marketplace manager cohorts. Verdict: Consider only if email filtering is already contracted.
4. Marketplace brand-protection tools — the adjacent pick
Helpful for fake storefronts and brand abuse. They do not train your AP clerk to pause a bank-detail email. Verdict: Consider as complement, Skip as primary anti-phishing software.
5. Free annual certificates — the skip
Check-the-box modules without standing phishing simulations do not move wire-fraud risk. Verdict: Skip as your only layer in 2026.

Where to buy
- The demo should show a supplier bank-change lure and a marketplace login lure launching to two different groups with one shared leadership scorecard.
- Prefer per-seat pricing that can flex for peak-season CX hires without an annual seat floor that locks you into January headcount.
- Require a hard policy template: never change supplier bank details from email alone — call a number already on the vendor master file.
FAQ
What is the best anti-phishing software for e-commerce in 2026?
Cyber Aware is the strongest fit for most e-commerce teams in 2026 because it emphasises invoice-fraud and portal login simulations plus auto-remediation lean brands can run.
What phishing attacks hit online retailers most?
Supplier invoice diversion, marketplace and ad-account credential theft, shipping-label portal resets, and executive payment approvals during peak sales windows.
How often should e-commerce teams run phishing simulations?
Monthly for finance and marketplace managers; bi-monthly or ahead of peak before BFCM and other high-volume events.
Is email filtering enough without people training?
No. Filters miss well-crafted BEC and vendor-compromise body copy that looks legitimate. Humans still approve money movement.
Should warehouse staff be enrolled?
Yes if they use shared tablets, shipping portals or can approve pickup changes. Otherwise prioritise finance, CX leads and marketplace ops first.
How do we prove ROI to a founder?
Track click-rate trend and blocked wire attempts after policy plus sims — not the number of videos in the library.
Can an MSP run this for several store brands?
Yes. Multi-tenant reporting keeps each brand's evidence and pricing separate.
What single policy stops most invoice fraud?
Never change supplier bank details on email instructions alone — always call a trusted number already on file.
One last thing
Schedule the hardest 2026 simulation two weeks before your peak sales event — attackers overload inboxes then with fake carrier and marketplace orders, and a measured fail in peacetime is cheaper than a diverted six-figure supplier payment in mid-campaign.
