NetGuardians overcomes the problems of analyzing billions of pieces of data in real time with a unique combination of technologies to offer unbeatable fraud detection and efficient transaction monitoring without undermining the customer experience or the operational efficiency and security in an enterprise-ready solution.
When it comes to data analytics, the more data the better, right? Not so fast. That’s only true if you can crunch that data in a timely and cost-effective way.
This is the problem facing banks looking to Big Data technology to help them spot and stop fraudulent and/or non-compliant transactions. With a window of no more than a hundredth of a millisecond to assess a transaction and assign a risk score, banks need accurate and robust real-time analytics delivered at an affordable price. Furthermore, they need a scalable system that can score not one but many thousands of transactions within a few seconds and grow with the bank as the industry moves to real-time processing.
AML transaction monitoring might be simple on paper but making it effective and ensuring it doesn’t become a drag on operations has been a big ask. Using artificial intelligence to post-process and analyze alerts as they are thrown up is a game-changing paradigm, delivering a significant reduction in the operational cost of analyzing those alerts. But accurate fraud risk scoring is a much harder game. Some fraud mitigation solutions based on rules engines focus on what the fraudsters do, which entails an endless game of cat and mouse, staying up to date with their latest scams. By definition, this leaves the bank at least one step behind.
At NetGuardians, rather than try to keep up with the fraudsters, we focus on what we know and what changes very little – customers’ behavior and that of bank staff. By learning “normal” behavior, such as typical time of transaction, size, beneficiary, location, device, trades, etc., for each customer and internal user, and comparing each new transaction or activity against those of the past, we can give every transaction a risk score.Read More

The below is an extract from an interview I ran in February 2019 during the EPFL Forward event.
NetGuardians is a Swiss Software Publisher based in Yverdon-les-bains that edits a Big Data Analytics Solution deployed Financial Institution for one key use case: fighting financial crime and preventing banking Fraud.
Banking fraud is meant in the broad sense here: both internally and externally.
Internal fraud is when employees misappropriate funds under management and external fraud is when cyber-criminals compromise ebanking applications, mobile devices used for payment or credit cards.
In the digital age, the means of fraudsters and cyber-criminals have drastically increased.
Cyber-criminals have become industrialized, professionalized and organized. The same technology they use against banks is also what gives us the means to protect banks
At NetGuardians we deploy an Artificial Intelligence that monitors on a large scale, in depth and in real time all activities of users, employees of the bank, but also those of its customers, to detect anomalies.
We prevent bank fraud and fight financial crime by detecting and blocking all suspicious activity in real time.
Jérôme Kehrli, how did you manage to convince a sector that is, in essence, very traditional, to trust you with your digital tools to fight against fraud?
Two different worlds, two languages, two visions?
The situation of the banks is a bit peculiar, the digitization and with it the evolution of the means and the behaviours of the customers in the digital age, was at the same time both a traumatic and a formidable solution.
The digital revolution was a traumatic because the banks, which by their very nature are very conservative, especially in Switzerland with our very strong private banking culture, were not prepared for the need to profoundly transform the customer experience of the banking world: to meet the customer where he is, on his channels, with mobile banking, this culture of all and everything immediately, with instant payments, the opening of the information system, with the explosion of the External Asset Managers model and external service providers with the PSD2 European standard, etc.
The digital revolution has imposed these changes, sometimes brutally, in banks and it is the source of a tremendous increase of the attack surface of banks.
But this same technology that spawned the digital revolution has proved to be the solution too.
Technology has made it possible to build digital banking applications that provide all of the bank's services on a mobile device.
Technology has made it possible to implement innovative solutions that secure the information system and protect client funds.
And in this perspective, Artificial Intelligence is really a sort of panacea: robot advisory, chatbots, personalization of financial advice and especially, especially the fight against financial crime: banking fraud and money laundering
In the end, if five years ago our solutions seemed somewhat avant-garde, not to say futuristic and sometimes aroused a bit of skepticism, today the banks are aware of the digital urgency and it is the bankers themselves who eagerly seek our solutions.
You support the digital shift of the banking sector.
Do banks sometimes have to change their way of operating, their habits, to be able to use your technologies?
(Do you have to prepare them to work with you?)
So of course the digital revolution profoundly transforms not only the business model but also the corporate culture, its tools, and so on.
At NetGuardians we have a very concrete example.
Before the use of Artificial Intelligence, banks protected themselves with rules engines. Hundreds of rules were deployed on the information system to enforce security policies or detect the most obvious violations.
The advantage with rules was that a violation was very easy to understand. A violation of a compliance rule reported in a clear and accurate audit report was easy to understand and so was the response.
The disadvantage, however, was that the rules were a poor protection against financial crime and that's why fraud has exploded over the decade.
Today with artificial intelligence, the level of protection is excellent and without comparison with the era of the rules.
But the disadvantage of artificial intelligence is that accurately understanding a decision of the machine is much more difficult.
At NetGuardians, we develop with our algorithms a Forensic analysis application that allows bankers to understand the operation of the machine by presenting the context of the decision.
This forensic analysis application, which presents the results of our algorithms, is essential and almost as important as our algorithms themselves.
This is a powerful application but requires a grip.
Tom Cruise in Minority Report who handles a data discovery application playing an orchestra conductor, it's easy in Hollywood, but it's not in reality.
In reality, we provide initial training to our users and then regular updates.
In the end, a data analysis and forensic application is not Microsoft Word. Our success is to make such an application accessible to everyone, but not without a little help.
In conclusion i would say that the culture transformation end the evolution of the tools do require some training and special care.
In general, what should a company prepare for, before making a digital shift?
In the digital age, many companies must transform their business model or disappear. Some services become obsolete, some new necessities appear.
We can mention Uber of course but also NetFlix, Booking, eBookers, etc.
For the majority of the industrial base, the digitalization of products and services is an absolute necessity, a question of survival.
Successful process and business model transformation often requires a transformation of the very culture of the company, down toits identity:
Among other things one could mention the following requirements:
- scaling agility from product development to the whole company level
- involving digital natives to identify and design digital services
- realizing the urgency or if necessary create a sense of urgency
- understanding the scale of the challenge and the necessary transformation. Some say "if it does not hurt, it is not digital transformation"
In summary I would say that a company is "mature" for digitalization if it is inspired by the digitalization of our daily life to adapt its products and services AND if it has the ability to execute its ideas.
Ideas without the ability to execute leads to mess, the ability to execute without the ideas leads to the status quo.
From there I would say that a company must prepare itself on these two dimensions, bring itself the conditions and resources required to identify and to design its digital products and those required to realize them.

The digitalization with its changes of means and behaviours and the induced society and industrial evolution is putting increasingly more pressure on banks.
Just as if regulatory pressure and financial crisis weren't enough, banking institutions have realized that they need to transform the way they run their business to attract new customers and retain their existing ones.
I detailed already this very topic in a former article on this blog: The Digitalization - Challenge and opportunities for financial institutions.
In this regards, Artificial Intelligence provides tremendous opportunities and very interesting initiatives start to emerge in the big banking institutions.
In this article I intend to present these three ways along with a few examples and detail what we do at NetGuardians in this regards.Read More

In parallel and in addition to BeCurious, the Empowerment Foundation launches in 2018 a project of curation files thematic through the bee² program.
Taking up the practice of curating video content, bee² means: exploring the issues that build our world, expand the perspectives of analysis, stimulate awareness to enable everyone to act in a more enlightened and responsible way facing tomorrow's challenges.
It's about bringing out specific issues and allowing everyone to easily discover videos the most relevant, validated by experts, on the given topic without having to browse many sources of information.
The three videos I contributed to are (in french, sorry):
- AI and Cybersecurity: Preventing Bank Fraud
- How does the Google self driving car work ?
- What are the limits of AI?
The three videos can be viewed directly on this very page below.Read More
