Which one is for you
DefendDomain compared to Memcyco
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).
Memcyco protects consumer-facing sites in real time while an attack is happening, with a focus on account takeover fraud at banks and large retailers. DefendDomain works earlier, finding the look-alike domains before they are used and taking them down, so the two sit at different points on the same attack.
- Built around
- Real-time protection for consumer-facing login and checkout
- 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 want the domain found and removed before anyone reaches it, rather than the damage contained while it runs.
- You want every page of your site watched, not just the pages an attacker is most likely to clone.
- Mail-only look-alike domains, with no website at all, are on your risk register.
- You want your own email authentication, DNS, TLS and web hardening 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 layer, which is the domains registered to impersonate you. Everything we build goes into finding them early and shutting them down fast.
Markers on every page, paired with content fingerprinting
Our Layer 2 markers sit on every page of your site rather than on the login page alone, and they are paired with Layer 3, which lifts distinctive phrases from your site and sweeps them across search engines continuously. Nobody in the set we benchmark against describes markers on every page paired with phrase fingerprinting.
We work before the attack, not during it
Real-time protection needs an attack in progress. We watch around 500 look-alikes of each of your domains from registration, and stream over 100 certificate transparency logs, so the domain is on the list long before anyone lands on it.
B2B fraud, not just consumer fraud
The impersonation that hurts a B2B company is a fake invoice from a look-alike 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 take it down.
The same questions, answered for both of us
What the product is built around
DefendDomain
100% focused on being the best in the world at detecting and removing look-alike domains. Five detection layers, all pointed at the same job
Memcyco
Real-time protection of consumer-facing sites, built around account takeover fraud and victim-level tracking during an attack
Look-alike domains that never host a website
DefendDomain
Treated as a finished weapon. Every registered look-alike is fingerprinted for MX, SPF, DKIM and DMARC, and the moment one is wired up to send email it resurfaces
Memcyco
Their published approach detects cloning and phishing setup against the protected site. Their material does not set out mail-record fingerprinting of look-alikes that host no website
When someone copies your website
DefendDomain
Invisible markers on every page fire when your content loads somewhere you do not control, and distinctive phrases from your site are swept across search engines continuously
Memcyco
They publicly describe an embedded code approach that detects cloning attempts against the site it is installed on. Their material describes a single embedded component rather than markers on every page paired with phrase-level search sweeps
Takedowns
DefendDomain
Unlimited on every plan, run across twelve channels in parallel, with the evidence pack frozen at initiation and the follow-up chased for you
Memcyco
Takedown automation is described as part of the platform. Volume and packaging are not published, so check your quote
Your own domains
DefendDomain
Layer 5 grades your email authentication, DNS hygiene and takeover risk, TLS, web hardening and exposure daily and gives you an A to F scorecard with per-finding remediation
Memcyco
Not part of the published platform. The coverage is protection during an attack rather than grading of your own configuration
How you buy it
DefendDomain
One flat annual subscription, quoted from a demo, sized for the mid-market. Self-managed or fully managed, your choice
Memcyco
Sales-led. Pricing is quote only and no price list is published

What each of us costs
Not everyone in this category publishes a price, so here is the shape of it rather than a number we cannot stand behind.
What Memcyco publishes
Memcyco does not publish a price list.
What moves the number
Customer-facing fraud tooling is usually sized against traffic and transaction volume rather than against the number of domains you own.
How DefendDomain charges
We size on your domain footprint rather than your traffic, so a good quarter for the business does not arrive as a bigger invoice. One annual subscription, all five layers.
What moving actually involves
There is no security agent to deploy and no data to migrate. The one thing that touches your site is the Layer 2 marker, and that is a copy-paste job rather than an integration. That makes this a shorter conversation than most security purchases, so here is the honest version of it.
These solve different halves of the same attack
Memcyco works at the moment a customer arrives on a fake page. We work at the moment the domain is registered and again when it is armed. Neither removes the need for the other.
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.
Nothing to rip out either way
We sit outside the perimeter and need no code on your checkout, so running us alongside customer-side protection is genuinely additive rather than a swap.
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's work happens at the point a customer lands on a page impersonating you. Ours happens earlier, when the domain is registered, when it is wired 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 embedded marker approach different?
Ours goes on every page rather than on the pages most likely to be cloned, and it is paired with a second layer that does not depend on an attacker copying your code at all. Layer 3 extracts distinctive phrases from your site and sweeps them across search engines continuously, with AI checking for paraphrase and partial copies, so a clone that strips your scripts or rewrites your text still surfaces.
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 look-alike 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 taking it offline.
Can DefendDomain detect a clone hosted somewhere completely different?
Yes, and that is the point of running two layers rather than one. Markers fire wherever in the world your content loads, including on free hosting platforms and on addresses that look nothing like yours. Content fingerprinting finds copies that search engines have indexed even when the markers have been stripped out.
