Visa Introduces Features to Prevent, Disrupt Payment Fraud
Visa has launched a suite of innovative security capabilities to help prevent and disrupt payment fraud, breaking new ground in cybersecurity and fraud prevention across Central & Eastern Europe, Middle East and Africa (CEMEA) at the Visa CEMEA Security Summit 2019 in Barcelona, Spain.
The forum brings together payment industry experts from risk, business and operational departments of financial institutions, merchants, processors and other payment service providers.
The new payment security services and capabilities help protect the integrity of the payments ecosystem by detecting and disrupting fraud threats targeting financial institutions and merchants.
The new features are available to Visa clients at no additional cost or sign-up, but through Visa’s continued investments in intelligence and technology. These add to the long list of benefits financial institution and merchant clients enjoy as participants in the Visa global payment network.
“Cybercriminals attempt to bypass traditional defenses by stealing credentials, harvesting data, obtaining privileged access, and attacking trusted third-party supply chains,” said Hector Rodriguez, Regional Risk Officer, CEMEA, Visa. “Visa’s new payment security capabilities combine payment and cyber intelligence, insights and learnings from breach investigations, and law enforcement engagement to help financial institutions and merchants solve the most critical security challenges.”
According to a global report by Forrester Consulting commissioned by Visa, ATM cashout attacks that exploit vulnerabilities among financial institutions and processors to remove fraud controls to withdraw money from cash machines fraudulently, and automated testing of values and credentials to gain unauthorized access to information and functionality called “enumeration attacks” were among the most prevalent account-related fraud types identified by respondents.
At the same time, card-not-present fraud that includes ecommerce, phone and mail orders was found to be less frequent but caused more damage to businesses—representing nearly 40% of fraud losses and operational costs. Managing payment fraud holistically is imperative to meet these challenges.
Protecting the Ecosystem from Threats
At the center of every Visa transaction is trust. As threats evolve, Visa’s payment security capabilities help to holistically protect the core components of the ecosystem—people, data and infrastructure—to maintain trust and connect the world through the most innovative, reliable and secure digital payment network. The new security capabilities add to existing protections and include:
Visa Vital Signs
Actively monitors transactions and alerts financial institutions of potential fraudulent activity at ATMs and merchants that may indicate an ATM cashout attack. To limit financial losses for financial institutions, Visa can automatically or in coordination with clients, step in to suspend malicious activity.
Visa Account Attack Intelligence
Applies deep learning to Visa’s vast number of processed card-not-present transactions to identify financial institutions and merchants that hackers may be using to guess account numbers, expiration dates and security codes through automated testing. The machine learning technology detects sophisticated enumeration patterns, eliminates false positives, and alerts affected financial institutions and merchants before fraudulent transactions begin.
Visa Payment Threats Lab
Creates an environment to test a client’s processing, business logic and configuration settings to identify errors leading to potential vulnerabilities. For example, Visa can verify if a financial institution is effectively validating cryptograms—dynamically generated codes unique to each transaction—for EMV® chip transactions.
Visa eCommerce Threat Disruption
A proprietary solution that uses sophisticated technology and investigative techniques to proactively scan the front-end of eCommerce websites for payment data skimming malware. Identifying potential website compromises limits the amount of time malware might be present on a merchant website and significantly reduces exposure of customer and payment data.
These capabilities complement Visa Payment Threat Intelligence, which provides actionable and informational cyber intelligence to clients and merchants worldwide. It offers timely intelligence reporting, technical delivery and educational materials. This includes alerts, analysis, technical indicators, and mitigations for potential cybercrime threats, account compromises and fraud.

Zoho Launches Nathu La Server
By Modupe Gbadeyanka
A designed-in-house server known as Nathu La has been launched by a global technology company, Zoho Corporation.
Nathu La is engineered with hardware-rooted security at every layer of the stack. Its indigenous IP-driven approach reduces dependency on external entities for security audits, firmware updates, and licensing continuity.
The solution aligns with open-source software principles and reflects Zoho’s broader commitment to building sustainable, secure, and scalable digital infrastructure. It also supports the growing global focus on digital sovereignty, local innovation ecosystems, and high-performance computing capabilities.
The platform was introduced by the company as part of a pivotal step in its journey towards building its full technology stack, from the hardware layer to software applications.
With Nathu La, Zoho has achieved equivalent performance with 12-18 per cent lower power consumption and 20-30 per cent lower total cost of ownership (TCO), thereby reducing inference costs.
The Nathu La server, comprising Intel® Xeon® 6 processors, was developed collaboratively with Intel, leveraging their enablement capabilities and technical expertise.
The design philosophy behind Nathu La is rooted in the Open Compute Project (OCP), emphasising modularity, thermal efficiency, and ease of maintenance. This enables Zoho’s data centres to significantly reduce total cost of ownership and power consumption.
Zoho plans to host its applications on the Nathu La server platform, enabling the company to optimise the full software-hardware stack for its specific workloads, reduce costs, improve performance, and strengthen data governance for its global customers. This will also help bring down inference costs for Zoho’s AI usage.
The Nathu La server motherboard and chassis platform is the result of five years of R&D across hardware, firmware, and systems management. Based on Intel® Xeon® 6 Processors, the server is designed to optimise performance for virtualisation (VM), High Performance Computing (HPC), AI inference, and storage applications. This results in improved performance of Zoho applications for end users.
The server features customised power delivery subsystems, an in-house DC-SCM (Data Centre Secure Control Module) design, and modular chassis options compatible with diverse end-user environments, offering flexibility across deployment types.
All modular components – including the DC-SCM and NIC (Network Interface Card) – were designed in-house by Zoho’s hardware engineering team and assembled through electronics manufacturing partners, enabling tighter integration and quality control across the platform. Over five patents have been filed covering advanced thermal management and cost-optimised server architecture designs.
“Zoho Corporation has invested in building its own technology stack from the ground up over the last three decades. The Nathu La server launch is in line with that goal.
“With our strategy of using contextual, right-sized models, running on our own platform, on our own servers, in our own data centres, we are compounding the benefits accrued from owning and operating our entire technology stack. This ensures that our solutions are more sustainable and accessible for businesses.
“These long-term R&D investments we are making at every layer of the stack are aimed at delivering customer value,” the Country Head for Zoho Nigeria, Mr Kehinde Ogundare, stated.
In 2020, Zoho established a small R&D team in Nagpur, a Tier 2 town in India, focused on projects such as server design and systems engineering.
Members of the Nathu La R&D team include hires from SETU – short for Students’ Engagement for Transformative Upskilling – an initiative designed to build a pipeline of industry-ready engineers, with a focus on advanced learning in Electronics System Design and Manufacturing (ESDM).

MTN Fintech Targets Credit Market With Direct Lending Plans
By Adedapo Adesanya
The financial technology arm of MTN is mulling a direct shift into lending after bringing on its parent company, MTN Group, as a major investor to help cushion against losses that have plagued the business.
According to MTN Group Fintech chief executive, Mr Serigne Dioum, the company wants to move beyond helping customers access loans through partners.
He said in markets where regulators allow it, MTN wants to lend directly and use its own balance sheet.
“We’ve expanded access to credit for more people, but we also want to move further up the lending value chain,” Mr Dioum told investors at the company’s capital markets day.
“Where appropriate, we will seek licences that allow us not only to facilitate loans but also to lend directly to customers and deploy our own balance sheet.”
This development is expected to create a shift in its current fintech model which provides financial services, including deposits, payments, transfers and digital wallets to individuals and small businesses via digital and mobile‑based platforms.
The company has applied for Payment Solution Service Provider and Payment Terminal Service Provider licences through MoMo PSB, its Nigerian fintech subsidiary. If approved, the licences would allow MTN to handle more payment processing, build merchant payment tools, deploy and manage POS terminals, and reduce its dependence on third-party processors.
Despite the opportunities present in the credit market, direct lending could give MTN a larger share of revenue, but it would also expose the company to credit risk, regulation and tougher competition with banks and digital lenders.
Mr Dioum said only about 4 per cent to 5 per cent of adults have access to formal credit across the African continent. In Nigeria, the funding problem is especially severe.
A 2025 report by the National Credit Guarantee Company said nearly 80 per cent of Nigerian MSMEs lack access to formal credit, while Stears has estimated the country’s MSME financing gap at about $236 billion.
For traders, small shop owners, transport operators and households, access to small loans can determine whether they restock inventory, pay suppliers, cover emergencies or expand a business.
In April, MTN Nigeria announced that its parent firm, based in South Africa, would acquire a 60 per cent stake in MoMo Payment Service Bank Limited (MoMo PSB) and Y’ello Digital Financial Services (YDFS) Limited.
The fintech units are currently loss-making, and this move will help MTN Nigeria to reduce financial risk and share future losses and investment burden. However, it will still keep a significant minority stake (40 per cent).

Meta Expands Business Agent to Instagram, WhatsApp, Messenger
By Aduragbemi Omiyale
The reach of the Meta Business Agent is being expanded to Instagram and other platforms of the social media giant.
Meta Business Agent is an artificial intelligence (AI) that allows business owners to attend to customers’ needs with ease.
Customers expect instant responses, but no team can be everywhere at once. This innovation handles such without hassles.
It helps businesses to answer questions specific to the business, makes product recommendations from the catalogue, books appointments, qualifies incoming leads, and closes sales.
More than one million businesses are already using a Meta Business Agent on WhatsApp and Messenger to respond to customers around the clock.
“We’re now expanding our Business Agent to businesses big and small globally, so within minutes you can have yours up and running, responding in your customer’s local language using your tone,” Meta said in a statement.
“We’re also expanding these agents to Instagram since businesses connect with their customers there, too. Businesses can activate their Business Agent here. Getting started with the Business Agent is free. In the coming months, businesses will access the agent through our paid subscription offerings, with options for businesses of every size,” it added.
Meta also stated that it is making it simpler for people to discover businesses powered by a Meta Business Agent directly on WhatsApp. It noted that starting soon, people will be able to find businesses by typing their name in the Search bar, or by sharing their phone number or contact card in chats with friends and family. This way, when more customers reach out, they get a quick, helpful response.
