Memcyco protects brands and their customers from website impersonation, phishing and account takeover. Banks, credit unions, airlines, retailers and hospitality companies use it to spot fake copies of their websites as they appear, see which customers have been exposed and stop attackers from using stolen credentials and card data on the real site.
Criminals clone a brand’s website, harvest the logins and payment details that victims type into it, then reuse them against the genuine service. Memcyco works on the brand’s own website and login flows to break that chain, and adds threat intelligence and takedown for impersonating sites, social profiles, ads and apps.

What Memcyco Does
Memcyco’s approach is to act while an impersonation attack is under way rather than after the fake site has been reported. Because it watches the genuine website, it can see an attack being prepared and tested, and catch phishing sites before they appear in threat databases. It works at the level of individual victims and attackers rather than aggregate alerts, so a bank can tell which customers typed their details into a fake page and protect those accounts. Data that victims hand over can be swapped for traceable decoys, which turns a stolen credential into a way of identifying the attacker. Takedown of impersonating assets elsewhere complements that protection.
Products
Digital Impersonation Threats And Account Takeover Protection
The core product protects brand websites and the people who use them. It detects attack preparation and testing, activity on impersonating sites, cross-site scripting and SEO poisoning, and raises Red Alerts with adaptive protection. On the login side it detects exposed users, credential stuffing, password brute force and suspicious logins. Marked decoy credentials, Decoy Data Deception Campaigns and Canary Credentials expose attackers, who can then be blocked along with at-risk user access.
Device Account Takeover Protection
This product covers attacks that happen on the victim’s own device. It protects against Man-in-the-Browser attacks, detects compromised sessions and compromised credentials, and protects against remote access fraud.

How It Works
Memcyco is agentless and needs no app installation or action from end users. It is deployed on the website or through a WAF or reverse proxy, and runs as fully managed SaaS on AWS, covering web and mobile authentication and environments with many brands and domains.
| Component | What it does |
|---|---|
| Nano-Defenders | Components embedded in the protected website that work through Sense, Correlate, Understand, Protect and Adapt stages. |
| Canary credentials | Decoy credentials are planted on impersonation sites; when an attacker tries them on the genuine login page, the attacker’s device is identified. |
| Data feeds | Event, alert and risk APIs and data feeds send infrastructure, user exposure, device and credential activity to SIEM and fraud tools, so security, fraud and digital business teams share the same attack context. |
