Using application-centric micro-segmentation to perform application segmentation ensures that security visibility and policy controls keep pace with rapid changes to both the environment and the applications running in it.

In the US, the financial cost of a data breach is rising year on year. IBM’s Cost of a Data Breach Report, is independently conducted annually by the Ponemon Institute. This year, the report included data from more than 15 regions, across 17 industries. They interviewed IT, compliance, and data protection experts from 477 companies. As a result, the true average cost of a data breach is more accurate than ever.
Crunching the Numbers: The Average Cost of a Data Breach
According to the study, the average cost of a data breach in 2018 is $3.86 million, which has increased by 6.4% since last year’s report.
While the risk of a data breach is around 1 in 4, not all breaches are created equally. Of course, the more records that are exposed, the more expensive and devastating a breach will be. A single stolen or exposed data record costs a company an average of $148, while 1 million, considered a Mega Breach, will cost $40 million. 50 million may be reserved for the largest enterprises, but this will raise the financial cost to $350 million.
Beyond a Ransom: The Hidden Cost of Data Breach
Although many businesses worry about the rise in ransomware, the cost of a data breach is about much more than any malicious demand from a hacker could be. The true cost can be broken down into dozens of areas, from security upgrades in response to the attack to a drop in your stock price when word of the breach gets out. Research by Comparitech found that companies tend to see a stock price slide of 42% following a breach. Other costly elements of a data breach include Incident investigation, legal and regulatory activity, and even updating customers. These all contribute to the escalating cost when you fail to adequately protect your company against a data breach.
The Ponemon study found that the largest cost comes from customer churn. The US sees the highest cost in the world in terms of lost business due to a data breach, more than two times the average figure, at $4.2 million per incident. Most analysts put this discrepancy down to the nature of commerce in the United States. In the US, there is far more competition and choice, and customer loyalty is both harder to hold onto and almost impossible to retrieve once trust is lost.
Customers also have more awareness of data breaches in the US, as laws dictate they must be informed of any issues as they are uncovered. This kind of reputational damage is devastating, especially in the case of a Mega Breach. In fact, 1/3 of the cost of Mega Breaches can be attributed to lost business.
Of course, there is also the fear that even if you manage to recover from a data breach, the worst is not over. The IBM study found that there is a 27.9% chance of another breach in the following two years after an attack, making your company extremely vulnerable unless you can make considerable changes, and fast.
Preparing Your Business for the Average Cost of a Data Breach
The numbers don’t lie. The speed and impact of data breaches is something to which every company, no matter the size, should be paying attention. There are definitely ways to protect your business and to position yourself responsibly for the worst case scenarios.
According to Verizon, 81% of all breaches exploit identity, often through weak passwords or human error. Malware can piggyback onto a legitimate user to get behind a physical firewall, which is why most IT professionals agree that even next-gen firewalls are insufficient. To limit the potential repercussions of this, all businesses need to be employing a zero-trust model.
With micro-segmentation, perimeters can be created specifically for the protection of sensitive or critical data. This ensures that all networks are considered not trusted. Using a granular approach to limit communications, and tagging workloads themselves with labels and restrictions. Containment of attacks is built into your security from the outset, by limiting the attacker’s freedom of movement and restricting ability for any lateral movement at all. As the financial impact of a data breach rises with the amount of data records stolen, this is a significant weapon to have at your disposal.
Rapid Response Can Limit the Cost of Data Breaches
Efficiency in identifying an incident as well as the speed of the response itself has a huge impact. Rapid response can save money, as well as proving to your customers that you still deserve their trust. According to the IBM report, the average time it took companies to identify the data breach was 197 days. Even once a breach was detected, the average time to contain it was a further 69. When it came to a Mega Breach – it could take an entire year to detect and contain.
With micro-segmentation, the visibility is immediate. All communications are logged, including East-West traffic. This includes private architecture, cloud-based systems, and even hybrid solutions. The best solutions will offer alerts and notifications in case of any unusual behavior, allowing you to stop threats in their tracks, before any damage has been done.
The quicker this happens, the less financial damage will be done. In fact, on average, companies who suffered a breach that managed to contain it within 30 days saved more than $1 million over companies who couldn’t. The larger the breach – the more significant these savings are likely to be.
Ensure You’re Fully Armed Against a Data Breach
The complex nature of most businesses IT systems explains the growing threat of cyber-crime, and the increasing financial cost of lax security holding us all to ransom. Traditional security systems are not enough to ensure adequate protection from a data breach, or rapid detection and response in case the worst happens.
Micro-segmentation offers granular flexible security that adapts to your exact environment, detecting and limiting the force of an attack, and providing the visibility and response tools you need to keep your customers loyal.

Understanding Attack Vectors
An attack vector is the way that an adversary can gain unauthorized access to your network or devices. Over the years, there have been dozens of different attack vectors, many of which have adapted and evolved over time to cause harm or hold companies hostage. Today, networks and organizations are interconnected using both private and public clouds leaving the door ajar for attack vectors that are more sophisticated than ever. What should smart businesses look out for, and how can they protect themselves?
The Evolution of Cyber Attack Vectors
Traditionally, having hardened perimeter security was enough to protect data centers. Layers of security to detect and prevent a breach coming in or out of data centers meant that you could ward off attack vectors to your infrastructure and hardware, which was almost exclusively on-premise.
The Cloud and mobile solutions have changed all of this. The reality for data centers today is keeping data private and secure while running an environment that spans public, private and hybrid clouds. Companies now use a mix of compute resources: Containers, Serverless Functions and VMs. However hackers are not just targeting your compute resources, they are sneaking in via routers and switches, or storage controllers, and sensors. From this vantage point, attackers can then scale their attack, compromising an entire network with lateral movements and connected devices. The MITRE ATT&CK Framework is a great resource to dive deeper on the different initial access attempts¹.
As the way we access the internet changes, cyber attack vectors adapt their own designs right alongside. Assuming that we are plugging all the holes on the IT side is not enough. The human factor has always been a key vulnerability in the security scheme. It has become more prevalent with the advance in end-user technology in recent years. Smartphones are a good example of this. Mobile attack vectors are not something that any organization had to be aware of a decade ago, and now they are an ever-present reality providing an easy gateway into many organizations.
While most people know not to click on dangerous links that arrive via SMS from unknown numbers, and no longer fall prey to email phishing campaigns like unexpected warnings of your bank password being changed, new attack vectors come from unexpected places. The recent Man in the Disk attacks on Android devices are something no one could have anticipated. This malware relies on vulnerabilities in third-party application storage protocols that are not regulated by sandbox restrictions through Android². This careless use of external storage can lead to potential malicious code injection, or the silent installation of unrequested apps to the user’s device. From there, the journey of an attacker to leverage this access to a deeper data center one is very short.
As technology evolves, there are more ways than ever for bad actors to launch attacks. Smart devices and Cloud-solutions only serve to increase the number of platforms which can be used for malicious intent.
Which Attack Vectors Are the Biggest Threats Today?
Email and phishing schemes have been the attack vectors of choice for a large amount of malicious attacks over the past few years. However, as simple attacks are becoming more recognizable, more complex threats are increasingly in vogue. Worryingly, the trend in malware is a movement away from reliance on human error, to clever attack vectors that can strike without any conscious act by the user whatsoever³. Man-in-the-Disk was just one example of this.
Administrator access could be the weak link when it comes to keeping your data centers safe overall. By accessing admin privileges, adversaries have access to the most valuable information you store, and can therefore cause the most harm. It’s important to think about the way your business works in a crisis when you’re planning preventive security measures. Used in an emergency, local authentication options are often not logged in the same way as your admins usual activity, and the credentials may even be shared across workloads and hosts for the sake of ease of use.
As well as smarter attack vectors, the growth in threats such as file-less attacks show that attackers are getting better at learning how to cover their tracks. 77% of cyber-crime in the US last year used a form of file-less attack⁴. Research shows that this type of malware is ten times as likely to succeed as traditional file based attacks, and helps attackers stay well beneath the radar.
AI is also an area that is likely to be compromised in the near future, with many companies creating chatbots and machine learning tools as the customer-facing representative of their websites and apps. As virtual assistants are built by humans, they are subject to the same gaps that human knowledge has. Studies are beginning to show that AI has problems with hallucinations and recognition⁵. Let loose on customer data and processes, it’s easy to see how advanced malware may slip through the cracks.
More than ever, in preparation for the next stage of intelligent malware, companies need to secure their data centers effectively against the latest attack vectors.
How Can Businesses Protect Themselves from Cyber Attack Vectors?
Keeping your IT environment safe from the latest attack vectors means being able to detect threats faster, and with better intelligence.
This starts with visibility. Being able to identify application flows across your entire infrastructure means that you have granular visibility across your whole IT stack. Dynamic deception tactics automatically trap attackers, even when the end-user isn’t aware of what is going on under the surface. Reputation analysis instantly uncovers anything suspicious or out of the ordinary, from unexpected IP addresses and domain names to file hashes within application flows. Even new attack vectors are isolated in real-time, with mitigation recommendations so that incident response is streamlined.
Ring-fencing, the separation of one specific application from the rest of the IT landscape is one way that companies are limiting the reach of the latest attack vectors from their most sensitive data or valuable assets. This and other kinds of micro-segmentation allow your business to truly limit the attack surface of any potential breach.
There are a number of benefits to this. Regardless of operating system limitations, communication policy can be enforced at the layer 4 transport level as well as the Layer 7 process level. By segmenting your flows by the principle of least privilege, even if a breach occurs, you ensure that it is quickly isolated, and attackers are unable to make lateral moves or scale their intrusion any further. When micro-segmentation is enforced alongside breach detection and threat resolution, even new attack vectors can quickly become a known quantity, and are unable to pose real danger.
Staying Safe Against Future Cyber-Attack Vectors
The way that data is stored and transferred is dynamic in and of itself. Our methods and processes are always changing as the capabilities of the cloud and the hybrid nature of our IT environments continue to grow. In direct response, attack vectors will never stay the same for long, and hackers will always have new tricks up their sleeve to compromise the latest solutions and catch us unaware. As well as current attack vectors that take advantage of IoT devices and no-fault infiltration, predictions for the future include AI-driven malware and an increase in file-less malware attacks, allowing hackers to hide their activities from detection.
The only solution is true visibility of all your applications and workflows. Using this mapping alongside segmentation policy that controls communication flows can restrict attackers in their tracks at the smallest sign of an anomaly. Even against new or unknown attack-vectors, these tools enable true threat resolution that can protect your entire infrastructure in real-time.

Micro-segmentation as we know it today has gone through several stages in the last few years, moving from a rising trend for securing software-defined data centers to a full-blown cyber security technology and a top priority on the agenda of nearly every CISO.
Built on the vision of securing the hybrid cloud and software defined data centers, we started our journey in 2013, thinking how to solve what in our opinion was a huge challenge for a market that did not exist at that time. In this post we’ll share how we created the micro-segmentation solution that is considered the best on the market – from vision to execution.
2015: First steps towards segmentation
Throughout the second half of 2015, we started delivering our micro-segmentation methodology after realizing that understanding how applications communicate inside the cloud was the key to success and as such – must be addressed first. “You can’t protect what you can’t see” wasn’t coined by GuardiCore but was immediately embraced by us when we started planning our micro-segmentation solution. We started developing our visibility solution Reveal, a visual map of all the applications running in the data center, all the way down to the process level. Reveal allows you to view applications and the flow they create in real time while also providing historic views. For the first time, admins and security teams were able to easily discover the running applications, one by one, and then review relations between the application tiers. Early releases supported general data center topologies as well as Docker containers.
2016: Gartner names micro-segmentation a top information security technology
We launched our segmentation solution at the RSA conference 2016 with a big splash. Reveal gained a lot of coverage and was well received by security teams who were lacking the proper tools to see the application flows in their data centers. It was one of the hottest security products at RSA 2016 and for a good reason!
Important to note that when micro-segmentation was introduced in Gartner’s Top 10 Technologies for Information Security in 2016 time in June 2016, many security professionals were unaware of the concept. In that report Gartner stated that to prevent attackers from moving “unimpeded laterally to other systems” there was “an emerging requirement for microsegmentation of east/west traffic in enterprise networks”. Enthusiasm was then at its peak, micro-segmentation was widely covered in the media and conferences dealing with the technology abound.
2017: Micro-segmentation for early adopters
Micro-segmentation was gaining traction as one of the most effective ways to secure data centers and clouds, but organizations learned the hard way that the path to meaningful micro-segmentation was full of challenges. Incomplete visibility into east-west traffic flows, inflexible policy engines and lack of multi-cloud support were among the most cited reasons. Throughout 2017 market penetration was around 5% of target audience and micro-segmentation was far from being mainstream. Andrew Lerner, Research Vice President at Gartner, noted in a blog post that “Micro-segmentation is the future of modern data center and cloud security; but not getting the micro-segmentation-supporting technology right can be analogous to building the wrong foundation for a building and trying to adapt afterward”.
That year GuardiCore tackled these challenges head on and based on the feedback we received from our growing customer base, we added flexible policy management and moved on from using only 3rd party integration to add native enforcement at the flow and process levels. Customers were able to move from zero-segmentation to native enforcement in 3 easy steps, based on revealing applications, building policies and natively enforcing policies.
2018: Our solution takes complexity out of micro-segmentation
Today, micro-segmentation serves as a foundational element of data center security in any data center. According to a Citi group’s report, cloud security is the number one priority among CISOs in 2018, with micro-segmentation the top priority in plans to purchase in this category. Concentrated effort on the part of organizations from different industries has resulted in better understanding of the technology. This year we were able to deploy micro-segmentation across all types of environments, from bare metal to virtualized machines, through public cloud instances and recently to containerized environments.
So if you are planning a micro-segmentation project let’s talk. We can show you how to do it in a way that is quick, affordable, secure, and provable across any environment.

While IT security teams often devote significant attention to perimeter protection, east-west traffic is outgrowing north-south traffic in both volume and strategic importance due to changes in data center scaling approaches, new big data analysis needs, and growing use of cloud services with a less defined perimeter. It’s more important than ever for IT security teams to develop their capabilities to prevent lateral movement in these types of environments. Read more about lateral movement security.
