Medallion Democratizes Data Centre Service in Nigeria
Engr. Ike Nnamani, managing director, Medallion Communications, a data centre operator in the country has attributed the emergence of his company’s data centre as the most connected data centre in the country to the democratization policy being implemented at its data centres.
Nnamani stated this in a chat with Nigeria Communicationsweek, explaining that they accommodate both small and big operators with cost effective pricing.
“We are able to provide a carrier neutral infrastructure where they are not afraid they are dealing with a competitor. Any service our customers are offering from our data centre, we at Medallion don’t go and start competing with them to offer such service. That gives them the confident that truly they are at carrier neutral place.
“We also enable every one of our customers to be treated equally no matter their size, whether you are big like MTN or small operator, we give every of them equal opportunity to do their business in efficient and cost effective way.
“We make sure we don’t fall below availability and the minimum standard. Of course pricing is important; I don’t think we are the most expensive in the market. You have to ensure that your client can afford the cost of the services you are offering them. Clearly, Medallion data centre is the most connected presently,” he said.
Nnamani frowned at the use of Tier certification as a marketing tool in the market, noting that the standard specified by Uptime Institute that manages those certifications are minimum standard that every data centre should be operating at even higher especially in our environment where companies almost operate their own power system.
“Uptime Institute is assuming for instant, if you have data centre in California and unfortunately because of the California fire issue that took place last year and your data centre had to be cut off from the public power supply, within the data centre do you have availability of power? That will last for 72 hours which is Tier 111 certification, which means you should be self- sustaining in power for 72 hours if there no public power supply.
“If you are operating a data centre in California with Tier 111 certification, you have to show outside of the traditional power supply that you have built redundancy, if it goes off you can self-sustain yourself either on battery back- ups, generators or some other means that will ensure that your data centre should be operational for 72 hours in case of Tier 111 certification.
“It becomes interesting when you bring such requirement into our climate, where you usually operate your data centre almost on private power supply, like our data centre we operate seven days straight on self -generating power, because the public power supply from PHCN is not available.
“So, how many Tier will you put such a data centre? From power perspective it becomes interesting when you look at markets like ours. There was a particular case we were on our self –generating power for more than five weeks running.
“Although there are areas that uptime institute looks at but the key point is power. They also look at redundancy; for instance, you should maintain dual power feed equipment to data centre.
“My take is that Tier certification is important because it gives a guide to minimum service level you should attain as a data centre operator. It is worth doing or attaining.
“Where I have a problem is when people start using it as a marketing tool as if it is a big deal then I have a problem with that because by default every data centre should operate at that standard,” he added.
Dr. Olubunmi Tunji-Ojo, minister of Interior, has announced the launch of an Online Visa Approval Center to eliminate bureaucratic bottlenecks and reduce corruption in the visa application process.
Commissioned by the President in December, the new system ensures that applicants no longer need to visit a visa office, know anyone in the system, or lobby for approvals.
At a stakeholders’ sensitisation workshop on the implementation of the Nigeria Visa Policy (NVP) 2025, yesterday in Abuja, Dr. Tunji-Ojo said the visa is considered a very important document by the government because it is an instrument of migration management and an instrument of economic development.
The minister explained that Nigeria has to strike a delicate balance between national security and, of course, the ease of migration.
“And we think that it’s something that we can do and something we will do.
“We don’t have a physical Visa Approval Center. If you apply for a Nigerian visa anywhere in the world, you do so online. We process it here in Nigeria, and if approved, you receive your e-visa in your email,” he explained.
To enhance efficiency, the government has set a 48-hour deadline for processing e-visas.
“It is unprofessional and unacceptable for the Nigeria Immigration Service not to approve or provide feedback within 48 hours,” the minister stated.
“It breaks my heart that people need to lobby to even get visas to Nigeria. It shouldn’t be so. It shouldn’t be.
“For anybody that is qualified, for anybody that wants to do legitimate activities in Nigeria, such people should be able to come to Nigeria easily. And this is why we are opening our space. Mr. President is interested in foreign direct investments.”
Further, he said Nigeria is interested in partnering with the rest of the world to develop its economy but, “We can’t do that when we allow bottlenecks to hold us down. So these reforms, basically, are aimed at opening our space, enhancing national security, and we hope that the primary responsibilities of the visa scheme will be achieved.”
Kemi Nandap, controller general, Nigeria Immigration Service (NIS), said the NIS would fully digitize its e-visa platform and reduce visa classifications from 79 to 44 to enhance accessibility, transparency, and efficiency in the new visa policy.
She said, “At the core of this policy is the new e-visa platform—a fully digitized, centralized system that revolutionizes how foreign nationals interact with our country’s entry procedures. As part of this transformation, the Nigerian Visa Policy 2024 underwent a comprehensive review, resulting in a significant reduction in visa classifications from 79 to 44.
“These categories have been logically grouped to simplify procedures, reduce complexities, and greatly improve the user experience. Importantly, we have maintained the original purpose and intent of each visa class throughout this reform.”
Mr. Takao Shimokawa, director general, Economic Development Department at the Japan International Cooperation Agency (JICA) has visited the National Information Technology Development Agency (NITDA) to discuss the forthcoming launch of the Nigeria-Japan Startup Hub Project.

This is in a strategic move to strengthen Nigeria’s startup ecosystem.
During his visit, Mr. Shimokawa was received by Mr. Dejo Olawunmi, director of IT Infrastructure Solutions at NITDA.
Their discussions focused on advancing technological innovation, fostering entrepreneurship, and enhancing venture capital development to support early-stage startups in Nigeria.
The Nigeria-Japan Startup Hub Project is designed to provide Nigerian startups with access to Japanese expertise, mentorship, and investment opportunities.
The initiative aims to create a collaborative environment where local entrepreneurs can scale their businesses by leveraging Japan’s advanced technology and business models.
By bridging Nigerian startups with Japanese investors and industry leaders, the project seeks to drive sustainable growth and innovation in Nigeria’s tech industry.
This partnership underscores the increasing economic and technological cooperation between the two nations, positioning Nigeria as a key player in the global startup landscape.
With the hub set to launch soon, stakeholders anticipate that it will provide critical resources for startups, enabling them to compete in the global market and contribute to Nigeria’s digital economy.
Kaspersky has identified and helped patch a sophisticated zero-day vulnerability in Google Chrome (CVE-2025-2783) that allowed attackers to bypass the browser’s sandbox protection system.
The exploit, discovered by Kaspersky’s Global Research and Analysis Team (GReAT), required no user interaction beyond clicking a malicious link and demonstrated exceptional technical complexity. Kaspersky researchers have been acknowledged by Google for discovering and reporting this vulnerability.
In mid-March 2025, Kaspersky detected a wave of infections triggered when users clicked personalised phishing links delivered via email. After clicking, no additional action was needed to compromise their systems.
Once Kaspersky’s analysis confirmed that the exploit leveraged a previously unknown vulnerability in the latest version of Google Chrome, Kaspersky swiftly alerted Google’s security team. A security patch for the vulnerability was released on March 25, 2025.
Kaspersky researchers dubbed the campaign “Operation ForumTroll”, as attackers sent personalised phishing emails inviting recipients to the “Primakov Readings” forum. These lures targeted media outlets, educational institutions, and government organisations in Russia.
The malicious links were extremely short-lived to evade detection, and in most cases ultimately redirected to the legitimate website for “Primakov Readings” once the exploit was taken down.
The zero-day vulnerability in Chrome was only part of a chain that included at least two exploits: a still-unobtained remote code execution (RCE) exploit that apparently launched the attack, while the sandbox escape discovered by Kaspersky constituted the second stage. Analysis of the malware’s functionality suggests the operation was designed primarily for espionage. All evidence points to an Advanced Persistent Threat (APT) group.
“This vulnerability stands out among the dozens of zero-days we’ve discovered over the years,” said Boris Larin, principal security researcher at Kaspersky GReAT. “The exploit bypassed Chrome’s sandbox protection without performing any obviously malicious operations – it’s as if the security boundary simply didn’t exist.
The technical sophistication displayed here indicates development by highly skilled actors with substantial resources. We strongly advise all users to update their Google Chrome and any Chromium-based browser to the latest version to protect against this vulnerability.”
Google has credited Kaspersky for uncovering and reporting the issue, reflecting the company’s ongoing commitment to collaboration with the global cybersecurity community and ensuring user safety.
Kaspersky continues to investigate Operation ForumTroll. Further details, including a technical analysis of the exploits and malicious payload, will be released in a forthcoming report once Google Chrome user security is assured.
Meanwhile, all Kaspersky products detect and protect against this exploit chain and associated malware, ensuring users are shielded from the threat.
This discovery follows Kaspersky GReAT’s previous identification of another Chrome zero-day (CVE-2024-4947), which was exploited last year by the Lazarus APT group in a cryptocurrency theft campaign.
In that case, Kaspersky researchers found a type confusion bug in Google’s V8 JavaScript engine that enabled attackers to bypass security features through a fake cryptogame website.
