How Virtualization Can Reduce Organisation’s Energy Costs

Virtualization can enable cost savings for organizations in multiple ways. This article explores those instances and points out how the overall power savings from virtualization can boost the environmental credentials of the private and public institutions that adopt it.

Each year, organizations devote a substantial amount of their budget to providing power for their operations. Energy costs are on the rise, and so is its consumption. With companies and public agencies running on an increasing number of devices, costs are expected to trend upward still.
The Nigerian context brings an extra dimension to the situation with energy costs in the country. For most businesses, power from the public grid isn’t enough. They often have to augment it with expensive alternatives. One estimate puts the total annual spend on power by businesses at ₦5 trillion.
Given this situation, it’s easy to see why businesses are on the lookout for legitimate ways to cut their power costs. Virtualization technology provides them with an effective way to do just that.
What Is Virtualization?
Virtualization refers to the creation of a virtual version of an actual thing, including Operating Systems, servers, storage devices, and other computer platforms and network resources.
The virtual versions sit atop the actual component and run just like them. Virtualization is done by deploying software that divides the physical resource into multiple virtual instances.
Here’s an example. Given a single physical server, multiple virtual servers could be created to run atop that server, and work just like it. Each of those virtual servers will perform the same functions that a single physical server would.
The same sort of thing happens with virtual Operating Systems. If you have virtualization software on your computer, you could create multiple Operating Systems—called Virtual Machines –that would run alongside the single Operating System that the computer previously had.
This ability to run several instances of a single component is at the core of the cost savings that virtualization can guarantee.
In the following sections, we explore some of the ways by which virtualization achieves lower costs for the organizations that adopt it.
Virtualization and Server Consolidation
Datacenters consume a lot of electricity. One widely cited report from 2018 (contained in the journal Science) suggests that they take up about 205 terawatt-hours of electricity annually—that’s about 1% of electricity consumed worldwide each year.
It follows that thanks to the energy costs associated with them, datacenters cost a lot to maintain.
A greater part of that expense–40% in one report–comes from running servers. Considering that many servers only have a single application running on them per time, it’s clear that a lot of spending is going into keeping those applications up. It also means that these servers are sitting idle most of the time, adding even more expense for little or no workloads.
With virtualization, these costs can be cut significantly. Virtualization enables the consolidation of the number of servers in a data center, enabling businesses to run several applications and Operating System workloads on a single server. In many cases, a company could have ten workloads running on one server; but it’s possible to have several times that number on one server.
This consolidation translates to a reduction in the number of servers needed, and a substantial increase in the utilization of server capacity. Capacity use could increase from about 15% (which is typical) to as much as 80%. Energy savings may increase by up to 80%, and energy costs are cut by a significant amount.
Scalability and Tailoring Resources to Current Needs
Energy costs can increase or decrease depending on the demand placed on the resources that consume power. These variations may occur over short periods, such as hours within a day. They could also be longer-term, such as the growth of a company.
If an organization experiences any of these instances, it may have to spend a lot on acquiring new capabilities. Its response in any of these cases may also be slowed down due to hardware handling issues and associated costs.
Virtualization can enable organizations to scale resources quickly and meet growing demand. Whether the demand on resources fluctuates over a short period, or resources have to be matched to company growth, creating virtual versions of those resources can take care of those needs.
Often, businesses may maintain ‘excess capacity’ just so they can utilize that capacity when the occasion calls for it. This happens when they are principally dependent on hardware or other actual components, and less on virtual versions of them. With virtualization, they can power on or power off capacity, and save the cost of dormant resources.
Virtualization’s Impact on the Environment
By reducing the amount of energy that has to be consumed per device, virtualization shrinks the potential impact that their use could have on the environment.
By one estimate, each server that is virtualized saves 7,000kWh of electricity and four tons of carbon dioxide emission per year. It cuts down the amount of space that’s required in a data center, thus reducing both the cost of managing it and its possible impact on the environment.
Another way in which virtualization helps mitigate the environmental impact of technology is its cutting down on hardware that needs to be decommissioned at the end of its lifespan. Electronic waste is known to be a major environmental hazard, and the failure to properly dispose of them could mean that they become a physical pollutant. If companies opt for virtualization instead of acquiring new hardware, they could drive down the number of hardware that will eventually be decommissioned.

Half of Global Companies Build SOCs to Enhance Cybersecurity, with a Focus on Human Expertise

Among the primary reasons for establishing a Security Operations Center (SOC) are strengthening cybersecurity posture, enabling faster detection and response and gaining a competitive edge.

Interestingly, despite the increasing demand for automated cybersecurity solutions, businesses rely on skilled security professionals to make key decisions, as human expertise remains essential for effective security management.
A Security Operations Center (SOC) is a dedicated organisational unit responsible for continuous monitoring and safeguarding of a company’s IT infrastructure. Its core mission is to proactively detect, analyse and respond to cybersecurity threats.
To identify the main drivers, strategic priorities, and potential challenges in SOC planning and implementation, Kaspersky has conducted a comprehensive global study involving senior IT security specialists, managers and directors from companies with 500 or more employees.
All participants operate without a SOC but have plans to establish one in the near future. The study spans 16 countries across APAC, META, LATAM, Europe, and Russia, providing valuable insights into the emerging trends and best practices in SOC development worldwide.
The findings of the research reveal that 50% of companies intend to establish SOCs to strengthen their cybersecurity posture, and 45% are motivated by the need to address increasingly sophisticated and dangerous threats.
Other drivers include budget optimisation, the necessity for faster detection and response, and the expansion of software, endpoints and user devices – factors that demand more comprehensive and layered security measures.
These are cited by 41% of organisations. Additionally, 40% seek better protection of confidential information, 39% aim to meet regulatory requirements and one-third (33%) expect SOC capabilities to provide a competitive edge. Larger enterprises tend to cite each of these reasons more often, reflecting the broader operational and regulatory pressures they experience.
Continuous monitoring becomes the leading SOC requirement
Among the key functions organisations plan to delegate, 24/7 security monitoring leads at 54%. This around-the-clock vigilance enables early detection of anomalies, prevents escalation and sustains cyber resilience in real-time. This demand highlights a strategic requirement for proactive risk management, as organisations aim to defend against persistent threats that can strike at any moment.
Companies intending to fully outsource SOC operations show a stronger interest in applying “lessons learned” methodologies, whereas those developing internal SOCs focus more on access management to maintain tighter control.
Human expertise drives SOC technology choices
While SOCs use advanced technology, the choices made by organisations show that human analysts are very important. Among the solutions that organisations plan to include in SOC are – Threat Intelligence Platforms (48%), Endpoint Detection and Response (42%) and Security Information and Event Management systems (40%) – sophisticated solutions that automate data collection and reduce operational load, however, they depend heavily on skilled security professionals who provide critical context, interpret complex findings and make final decisions when guiding appropriate responses.
Other solutions chosen include Extended Detection and Response (38%), Network Detection and Response (37%) and Managed Detection and Response (33%). Large enterprises tend to adopt more technologies (5.5 per SOC on average), while smaller ones integrate fewer (3.8).
“To successfully build a SOC, companies must prioritise not only the right mix of technology but also the careful planning of processes, clear goal-setting and effective resource distribution.
“Well-defined workflows and continuous improvement are essential to ensure that human analysts can focus on critical tasks, making the SOC a proactive and adaptable component of their cybersecurity strategy,” comments Roman Nazarov, Head of SOC Consulting at Kaspersky.

Nigerian Terra Industries Secures $11.8m for Expansion

Terra Industries, a Nigerian defence technology startup, has raised $11.75 million to expand its development of defensive systems that protect critical facilities across Africa.

The fundraising round was led by Silicon Valley venture firm 8VC, which was founded by Palantir co-founder Joe Lonsdale.
Other investors in the round include Valour Equity Partners, Lux Capital, SV Angel, and Nova Global, as well as African-focused funds Tofino Capital, Kaleo Ventures, and DFS Lab.
Terra Industries, founded in Abuja by Nathan Nwachuku and Maxwell Maduka, provides multi-domain security solutions for both air and land. Its solutions are intended to detect and respond to threats including terrorism, sabotage, and armed attacks on infrastructure.
The company’s product portfolio includes surveillance drones, ground-based robotic systems, and fixed monitoring towers deployed around sensitive locations.
Co-founder and CEO Nathan Nwachuku said the company has now fully embraced its identity as a defence-focused startup, citing the growing urgency of security challenges across Africa.
He said safeguarding critical infrastructure from terrorist threats has become unavoidable.
Nwachuku argues that protecting Africa’s infrastructure requires a different approach, one that combines local manufacturing, end-to-end system control, and software capable of independently identifying and responding to threats over large areas.
The company aims to position itself as a defence prime, similar to the role played by firms such as Anduril Industries and Palantir in the United States.
Nwachuku also disclosed that the company had earlier raised $800,000 in pre-seed funding.
With the new funding, Terra plans to increase manufacturing capacity within Africa, establish additional defence production facilities, and expand its artificial intelligence and software teams.
While software offices are planned for San Francisco and London, the company said manufacturing operations will remain on the continent.

Kaspersky Warns Telecom Threats from 2025 will Carry into 2026 as New Technology Adds New Risk

Kaspersky Security Bulletin reviews what shaped telecom cybersecurity in 2025 and what is likely to persist in 2026. Advanced Persistent Threat (APT) activity, supply-chain compromise, DDoS disruption and SIM-enabled fraud continued to pressure operators in 2025, while newer technology deployments introduce additional operational risk.

In 2025, telecom operators faced four broad threat categories. Targeted intrusions (APTs) continued to focus on gaining stealthy access to operator environments for long-term espionage and leverage through privileged network positioning.
Supply chain vulnerabilities remained an entry point: telecom ecosystems rely on many vendors, contractors and tightly integrated platforms, so weaknesses in widely used software and services can provide a path into operator networks. Finally, DDoS remained a practical availability and capacity problem.
Kaspersky Security Network showed that last year, between November 2024 and October 2025, 12,79% of users in the telecommunications sector encountered web threats and 20,76% faced on-device threats. 9,86% of telecom organisations worldwide experienced ransomware.
At the same time, the telecommunications sector is moving from rapid technological development to broad implementation — and the report argues that this shift creates new opportunities and new operational risks for 2026.
Kaspersky highlights three areas where technology transitions could introduce disruption if rolled out unevenly or without strong controls: AI-assisted network management, where automation can amplify configuration errors or act on misleading data; post-quantum cryptography transitions, where rushed deployment of hybrid and post-quantum approaches could cause interoperability and performance issues across IT, management and interconnect environments; and 5G-to-satellite integration (NTN), where expanding service footprints and partner dependencies introduce new integration points and potential failure modes.
“The threats that dominated 2025 — APT campaigns, supply chain attacks, DDoS floods — aren’t going away. But now they intersect with operational risks from AI automation, quantum-ready cryptography, and satellite integration.
Telecom operators need visibility across both dimensions: maintaining strong defences against known threats while building security into these new technologies from day one. The key is continuous threat intelligence that spans from endpoint to edge to orbit,” said Leonid Bezvershenko, senior security researcher at Kaspersky Global Research & Analysis Team.
