The #1 security threat is already inside your network.

Invest in Gyomo

The vast majority of data breaches start with social engineering - when people, not computers, are compromised. People clicking on phishing emails are the #1 cause of data breaches.   

A simple little email. Maybe you got a notice from the IRS. Or someone wants to share a something with you in DropBox. Perhaps your account is about to be suspended, and you need to act now! People are curious and a little too trusting. It’s our basic human nature that makes people the weakest link inside any network. 

Phishing is an attack on human nature -- at home, or at work -- even in big name brand names that you expect to be safe and protected. Home Depot, Sony, Hillary Clinton's presidential campaign, The Washington Post... Every one of these companies was breached with a phishing email that someone clicked on. And economic losses from data breaches are expected to top $2 trillion next year.

Companies try desperately to protect themselves, and collectively spend $1 billion every year training employees not to click on suspicious links. But, even with the current industry-leading training, 23% of people will continue to click on phishing emails... That's terrible!  

It's why many computer security people often say, “You can’t patch the human.”  

As a result, companies spend billions more to block and filter the internet from their employees. This is great for security, but terrible for productivity. I spent 10 years at Bank of America in this type of environment, where it took one to three days to get access to a new website, just to do my job. It was incredibly frustrating.

These two approaches, filtering and training, are our competition, and combined serve a $3 billion market, but they fail to meet the basic need of the customers.

Gyomo Has the Solution

Gyomo has a different approach that brings these two worlds together. It's call "Just-in-Time Training".

We utilize Machine Learning, Gamification, and Crowdsourcing to patch the human and secure the network. Gyomo provides training when people need it most… at the exact moment they click on a link.  

We use real phishing links that people are actually clicking on right then. This training provides the real world experience that simulated phishing just can’t, and we use crowdsourcing to stop phishing attacks before breaches occur.  We do all of this in less than 60 seconds, 2- to 3-times a week. That’s not just better training, it’s better learning, and better security.

The How and Why of Gyomo

How We Do It...

Gyomo’s patent-pending approach creates a prediction market for cybersecurity phishing attacks. Specifically, when a user clicks on a link that would take them to a potential phishing website (not on a whitelist), Gyomo steps in. 

Gyomo takes a screenshot of the website, gathers security data (form fields, hidden forms, embedded scripts, offsite links, cross site scripts, etc.), URL metadata (geoip, whois, dns, ssl, etc.), and scores the page based on a machine learning scoring algorithm. This score has an extremely high degree of confidence in the provenance of the website (good or bad) 96% of the time. Websites can be automatically blocked or allowed 19 times out of 20.  This level of accuracy and confidence is not uncommon for AI whitelists, but it can be extremely frustrating when you get erroneously blocked, and downright disastrous when you are allowed access to a malicious website.

The real power of Gyomo is in what it does with that remaining 4%, that one in 20 websites of which Machine Learning isn't very confident of its assessment. Gyomo presents a screenshot image of the website and relevant security information to a crowd of users. Those "peers" will have just received training about how to spot deceptive elements on websites like the one they’re about to see. The peers, armed with this additional security context and awareness, are prompted to asses the merits of this page and choose to approve or block it. Not only does this re-enforce the training with real world threats, it provides up to the minute, on-demand supervision for machine learning.

Why We Do It...

We care about the social engineering epidemic. It’s not only the hours of boring training we have personally suffered through. And it's not all the wasted time when legitimate websites were erroneously blocked. No. 

We have seen the gut wrenching despair when people click on phish and only afterward realize what they did - to themselves and to the company. 

No one should have to go through that.  

So we are on a mission to patch the human, and secure the network.

Why Now...

The market has been stuck on a treadmill - churning out the same ineffective solutions.  Phishing is getting worse, spear phishing is more effective than ever, and regulations (like GDPR) are forcing companies to get serious about preventing data breaches in the first place. The only effective choice is to cut off the internet, but that's just not practical.  

Enter Gyomo.  

Just-in-time training is dramatically more effective, and crowdsourcing makes reviews and escalations for potentially erroneously blocked websites near instantaneous. It is the solution the market has been demanding, without knowing exactly what it would look like.

Our Product

Current State

Gyomo has assessed the market, identified the minimum viable product based on market demand, conducted POCs, and acquired customers for pilots. In addition, we are currently working with Symantec to integrate with their ProxySG, which would allow Gyomo to be a turn-key solution aligned with one of the largest security gateway providers in the world.

With growing customer demand and integration on the horizon, Gyomo is in need of a monetary infusion to allow for the immediate hiring of technology staff to complete the build of the product that our customers desire, and to support the integration efforts with Symantec.

Recent Activities

  • Joined Startupbootcamp FinTech & Cybersecurity Accelerator
  • Established sales pipeline for European market
  • Obtained Letter of Intent from Vivat
  • Obtained Letter of Intent from PGGM
  • Actively working with Symantec on integration, based on introduction / request from Rabobank
  • Continue discussions with other potential customers (ING, KPN, etc)

Key Differentiators

Train for Real

Gyomo uses the same phish that are sophisticated enough to slip through network filters and convincing enough to entice employees. Gyomo uses those real phish for training, in a safe environment.

Block the Threat

Gyomo uses the collective wisdom of freshly trained people to identify and block malicious sites, transforming your #1 security vulnerability into a strong force actively working together in the defense of your network, blocking new threats right as they arise.

Seamless Integration

Using the standard iCap protocol, Gyomo integrates seamlessly with existing proxy servers, and can be utilized with or without existing training solutions.

Just In Time

Gyomo's solution provides training when you need it most. Right when someone clicks on a suspicious link Gyomo delivers short, focused gamified training that matches the attack. Even guidance on zero-day exploits is available with the Gyomo solution. Critically, this happens before a malicious website is loaded on a users machine.


Gyomo utilizes crowdsourcing to scale beyond the competition. Productivity decreases while waiting for security approvals, but the efficiency and wisdom of the crowd allows for faster access to websites that would otherwise take hours to approve, with the added benefit of reduced burden on your security staff.

The Opportunity

Current phishing solutions focus on either blocking known threats, or training users to avoid threats. The combined annual US spend on these two approaches is over $3B, with a 13% annual growth projected. However even with this significant spend:

  • Over 90% of all data breaches start with a phishing attack
  • Cybercrime costs continue to increase

    • $400 billion lost globally in 2015 (Lloyds of London)

    • $2.1 trillion estimated worldwide losses in 2019 (Juniper Research)

  • After training 23% of people will still click on phishing links (PhishMe)

  • 28% of phishing breaches were targeted attacks (Verizon)


Gaps In Current Solutions

Secure Web Gateways

Block known algorithmic threats, do little to protect against social engineering attacks, and do nothing in the way of training.

Security Awareness Training 

Provide simulated phish for training that have little resemblance to real attacks, and do nothing in the way of protection.
