Memcyco at a glance
Memcyco protects the login and checkout pages your customers actually land on, which places it alongside fraud tooling as much as Digital Risk Protection (DRP).
DefendDomain works earlier, finding lookalike domains as they are registered or set up, and getting them taken down when they are used, so the two sit at different points on the same attack.
- Memcyco is built around
- Real-time protection for consumer-facing login and checkout
- Typically sold to
- Enterprise, consumer-facing
- Typical annual cost
- Quote only, no public pricing
Choose Memcyco if
- You run a high-volume consumer login or checkout and account takeover is the headline risk.
- You need to identify individual affected customers while an attack is running.
- Showing your own customers a trust signal on the real site is something you want to offer.
- Your fraud team, rather than your security team, owns this budget.
Choose DefendDomain if
- You are B2B, and the fraud that costs you money is a fake invoice rather than a consumer account takeover.
- You would rather find the fake domain and get it taken down than contain the damage while it runs.
- You want to choose which pages carry the website marker, and have your wording searched for across the web.
- Lookalike domains set up only to send email, with no website at all, are on your risk register.
- You want your own domains' email security, DNS, certificates and website settings graded daily.
What Memcyco does well, and who should buy them
Taken from what Memcyco publishes about its own product. If this is the shape of your problem, they are a reasonable buy and we will say so.
Victim-level visibility during an attack
Identifying which individual customers have been exposed, while it is happening, is a genuinely hard problem and a real capability. If you run a large consumer login, that granularity has clear value.
Customer-facing trust signals
Giving your own customers a way to tell the real site from a copy is a distinctive approach to the problem, and it works on the half of the attack a security team cannot otherwise reach.
Account takeover as the organising problem
Their platform is built around consumer account takeover rather than brand abuse generally, which is the right shape for a bank or a high-volume retailer.
Where DefendDomain goes deeper
We work on one problem: web addresses made to look like yours, and copies of your website. We find them, tell you which can send email or show a copy of your site, and get them taken down when they are used against you.
The website marker, plus searches for your wording
The optional website marker can go on any page you choose, not only the login page: a small script or a 1×1 image that reports when a copy of the page loads somewhere else. We pair it with web searches for distinctive phrases from your site, so a copy that strips the marker can still be found.
We work before the attack, not during it
Protection during an attack needs an attack in progress. We watch around 500 lookalikes of each of your domains, re-checked every hour, and 100+ public certificate logs as entries appear, so a fake domain can be found before anyone lands on it.
B2B fraud as well as consumer fraud
The impersonation that hurts a B2B company is a fake invoice from a lookalike supplier domain, or a cloned site that never touches a login page at all. That attack has no consumer victim to protect in real time, and the answer is to find the domain and get it taken down.
The same questions, answered for both of us
What the product is built around
DefendDomain
Finding web addresses made to look like yours and getting them taken down: lookalike domains, new certificates, copies of your website and of your wording, plus a daily check of your own domains
Memcyco
Real-time protection of consumer-facing sites, built around account takeover fraud and victim-level tracking during an attack
Lookalike domains that never host a website
DefendDomain
We check the email set-up (MX, SPF, DKIM and DMARC records) of every registered lookalike. When one is set up to send email, we flag it, even if it has no website
Memcyco
Their published approach detects cloning and phishing setup against the protected site. Checking a lookalike's email set-up (MX, SPF, DKIM and DMARC records) and flagging when it can send email is not listed in their public material as of September 2026
When someone copies your website
DefendDomain
The optional website marker (a small script or a 1×1 image on the pages you choose) reports when a copy of a page loads somewhere else, and we search the web for distinctive phrases from your site
Memcyco
They publicly describe an embedded code approach that detects cloning attempts against the site it is installed on. Web searches for your wording are not listed in their public material as of September 2026
Takedowns
DefendDomain
Unlimited on Pro and Enterprise. One click sends the evidence to up to 12 places at once, with automatic follow-ups to the host, registrar and registry

The facts your vendor review will ask for
About DefendDomain only. Check the same points with any vendor on your shortlist.
- What we check
- Around 500 lookalikes of each of your domains across 240+ domain endings, re-checked every hour. 100+ public certificate logs, watched as entries appear. Copies of your website and of your wording. Your own domains, checked daily and graded A to F.
- Where a takedown goes
- One click sends the evidence to up to 12 places at once: the registrar, the host, the email provider the domain sends through, an abuse-report network, blocklists and threat feeds, browser warning lists and search engines. Not every place applies to every attack: a domain with no website has nothing for a search engine to remove.
- Follow-up
- Automatic. We chase the host and registrar again at 48 and 96 hours, go to the registry at 120 and 168 hours, and tell you if nothing has moved after 30 days. Most takedowns take between 2 and 96 hours.
- Who approves a takedown
- On Pro, someone on your side confirms it is a live attack and approves it with one click. On Enterprise, our analysts check every alert and run the takedowns. Takedowns are unlimited on both.
- Alerts
- Email, Slack, Microsoft Teams, SMS, webhook, Splunk, Microsoft Sentinel and Wazuh.
- Security and data
- ISO 27001 certified (certificate 535732026) and Cyber Essentials certified. UK GDPR and EU GDPR. Our main database is hosted in London (AWS eu-west-2).
- Which plan suits whom
- Pro suits companies that approve takedowns themselves. Enterprise covers unlimited domains and brands, run by our analysts.
- Price and contract
- Pro is an annual plan with 5 domains included, priced by the number of domains you protect. Enterprise is priced to your needs. Both are annual: a 12-month minimum, renewing each year unless you give 30 days' notice. We do not publish the Pro price yet.
We call you within one working day to talk it through.

What each of us costs
Most vendors in this category do not publish a price list. This is how each of us charges.
What moving actually involves
There is no software to install and no data to move. Lookalike monitoring, certificate watching and the daily check of your own domains need only your domain names. The website marker is optional: a small script or a 1×1 image on the pages you choose.
Step 1
These solve different halves of the same attack
Memcyco acts when a customer lands on a fake page; DefendDomain acts earlier, when the domain is registered, set up to send email or given a website. Neither removes the need for the other.
Step 2
Ask which half you are currently blind to
If you can see victims landing on clone pages but cannot see the clones being built, that is a detection gap upstream. If you know about the domains but not about the customers reaching them, it is the other way round.
Step 3
Nothing to remove either way
We sit outside your systems and need no code on your checkout (the website marker is optional), so running us alongside customer-side protection adds to it rather than replacing it.
Questions buyers ask us about Memcyco
Is Memcyco an alternative to DefendDomain?
Not really, and the companies that get the best result from either tend to understand why. Memcyco acts at the point a customer lands on a page impersonating you; DefendDomain acts earlier, when the domain is registered, when it is set up to send email, when a certificate is issued, and when your content appears somewhere it should not be. If your problem is that customers are reaching fake pages, you may want both. If your problem is that fake domains exist at all and nobody spots them for weeks, start with detection.
How is DefendDomain's website marker different?
Ours is optional and goes on the pages you choose, as a small script or a 1×1 image. It is paired with a second check that does not depend on an attacker copying your code: we take distinctive phrases from your site and search the web for them, with AI checking for reworded and partial copies, so a copy that strips your scripts or rewrites your text can still be found.
We are B2B. Is consumer fraud protection relevant to us?
Mostly not. If you do not run a large consumer login, real-time victim tracking has little to act on. The B2B version of this attack is a lookalike domain sending invoices to your finance team or your suppliers, or a copy of your site used to phish your own staff, and both are answered by finding the domain early and getting it taken down.
Can DefendDomain detect a clone hosted somewhere completely different?
Yes, and that is why we use two checks rather than one. The website marker reports wherever a marked page loads, including on free hosting platforms and on addresses that look nothing like yours. Searching for your wording finds copies that search engines have indexed, even when the marker has been stripped out.
