What Is Endpoint Protection?
How Does Endpoint Protection work?
Types of Endpoint Protection: EPP vs. EDR vs. XDR
Endpoint protection solutions are now commonly referred to as endpoint protection platforms (EPP), which are suites of cloud-based endpoint security solutions that provide more robust protection than individual endpoint security products like antivirus software. Legacy endpoint security is known for continuously scanning endpoints to identify malicious files, which can slow down performance.
Endpoint protection platforms may also provide the ability to detect and block malicious activity, and investigate and remediate any incidents that evade protection controls. This is known as endpoint detection and response (EDR). EDR continuously monitors end-user devices to detect and respond to cyberthreats like ransomware and malware.
The next evolution of endpoint protection is known as extended detection and response (XDR). XDR is a newer approach to endpoint security and offers improved protection, detection and response by integrating not just endpoint data but data from any source, such as network, cloud data or third-party data.
The Evolution of Endpoint Protection
1980s: Antivirus
Endpoint security has evolved beyond the basic capabilities provided by antivirus tools back in the 1980s, which scanned endpoint files for malware.
2000s: Next-Generation Antivirus (NGAV)
To combat new forms of malware, machine learning and behavioral threat protection was introduced to create more effective next-gen antivirus in the early 2000s.
2010s: Endpoint Protection Platform (EPP)
EPP combines antivirus or next-gen antivirus, personal firewall, encryption, USB device control, vulnerability assessment and more to deliver a full platform to stop malware from penetrating endpoints.
2015: Endpoint Detection and Response (EDR)
Gartner Analyst Anton Chuvakin coined the term "endpoint threat detection and response" to describe "the tools primarily focused on detecting and investigating suspicious activities" on endpoints in 2013. This name had evolved to endpoint detection and response by 2015.
2021: Extended Detection and Response (XDR)
While the concept of XDR was first introduced in 2019 by Palo Alto Networks, XDR is considered an emerging technology that is quickly gaining traction in the endpoint security market. While most technology providers now offer endpoint security offerings that combine EPP/EDR capabilities, most do not offer a true XDR solution that combines many data sources into one platform for analysis and remediation.

What is Endpoint Security?
Endpoint security, or endpoint protection, is the cybersecurity approach to defending endpoints – such as desktops, laptops, and mobile devices – from malicious activity.
According to Gartner, an endpoint protection platform (EPP) is a solution used to “prevent file-based malware attacks, detect malicious activity, and provide the investigation and remediation capabilities needed to respond to dynamic security incidents and alerts.”
What’s considered an endpoint?
An endpoint is any device that connects to the corporate network from outside its firewall. Examples of endpoint devices include:
- Laptops
- Tablets
- mobile devices
- Internet of things (IoT) devices
- Point-of-sale (POS) systems
- Switches
- Digital printers
- Other devices that communicate with the central network
Why Endpoint Security is Important
An endpoint security strategy is essential because every remote endpoint can be the entry point for an attack, and the number of endpoints is only increasing with the rapid pandemic-related shift to remote work.
How Endpoint Protection Works
Endpoint protection solutions work by examining files, processes, and system activity for suspicious or malicious indicators.
Endpoint Protection Software vs. Antivirus Software
Endpoint security software protects endpoints from being breached – no matter if they are physical or virtual, on- or off-premise, in data centers or in the Cloud.
Antivirus is often part of an endpoint security solution and is generally regarded as one of the more basic forms of endpoint protection. Instead of using advanced techniques and practices, such as threat hunting and endpoint detection and response (EDR), antivirus simply finds and removes known viruses and other types of malware.
Core Functionality of an Endpoint Protection Solution
Endpoint security tools that provides continuous breach prevention must integrate these fundamental elements:
- Prevention: NGAV
Next-generation antivirus (NGAV) closes that gap by using more advanced endpoint protection technologies, such as AI and machine learning, to identify new malware by examining more elements, such as file hashes, URLs, and IP addresses.
- Detection: EDR
To prevent silent failures, an Endpoint Detection and Response (EDR) solution needs to provide continuous and comprehensive visibility into what is happening on endpoints in real time.
- Managed Threat Hunting
Managed threat hunting is conducted by elite teams that learn from incidents that have already occurred, aggregate crowdsourced data, and provide guidance on how best to respond when malicious activity is detected.
- Threat Intelligence Integration
To stay ahead of attackers, businesses need to understand threats as they evolve. Sophisticated adversaries and advanced persistent threats (APTs) can move quickly and stealthily, and security teams need up-to-date and accurate intelligence to ensure defenses are automatically and precisely tuned.
A threat intelligence integration solution should incorporate automation to investigate all incidents and gain knowledge in minutes, not hours. It should generate custom indicators of compromise (IoCs) directly from the endpoints to enable a proactive defense against future attacks.

- Machine Learning
- Enhanced Manageability

Traditional vs. Cloud-native platforms
EPP vs. EDR
Endpoint detection and response (EDR) is just one component of an endpoint protection platform. On the other hand, an endpoint protection platform is made up of many cybersecurity technologies, including next-gen antivirus, threat intelligence, vulnerability management, and EDR.
A fully-featured EPP integrates an EDR solution to offer detection capabilities. Baking in EDR allows an endpoint protection platform to mitigate a breach that is uncovered. This could mean containing the exposed endpoints to stop the breach in its tracks, allowing remediation to take place before damage occurs. Read EPP vs. EDR >

EPP VS. EDR
When evaluating their cybersecurity needs and options, many organizations may find themselves asking:
Which is better: An endpoint protection platform (EPP) or an endpoint detection and response (EDR) solution?
In fact, this is a false choice. EPP and EDR are two critical and distinct components within a comprehensive cybersecurity strategy. While the two are closely related, they cannot be used interchangeably; nor does having one lessen or negate the need for the other.
In this article, we explore the relationship between these two crucial cybersecurity capabilities and address some of the most common misconceptions that organizations may have as they navigate the complex and crowded security solution landscape.
What is an endpoint protection platform (EPP)?
An endpoint protection platform (EPP) is a suite of endpoint security technologies such as antivirus, data encryption and data loss prevention that work together on an endpoint device to detect and prevent security threats like file-based malware attacks and malicious activity. They also have the capability to provide investigation and remediation in response to dynamic security incidents. Advanced EPP solutions use multiple detection techniques and are mainly cloud-managed and assisted by cloud data.
What is endpoint detection and response (EDR)?
Endpoint detection and response (EDR), also referred to as endpoint detection and threat response (EDTR), is an endpoint security solution that continuously monitors end-user devices and workloads to provide continuous and comprehensive visibility into what is happening on endpoints in real time. This allows cybersecurity teams to quickly and effectively detect and respond to cyber threats like ransomware and malware.
3 Common Misconceptions About EPP and EDR
Misconception 1: Organizations must choose between EPP and EDR.
Truth: Organizations need not make a binary choice between EPP or EDR
Misconception 2: EPP is a passive form of prevention.
Truth: EPP stands for endpoint protection platform, not passive prevention.
Misconception 3: A standalone EDR is enough.
Truth: An EDR solution helps security teams understand what is happening across the network at the endpoint level, which can in turn help them identify and remediate attacks. However, to defend against most modern cyberattacks, it is necessary to employ a much broader and more comprehensive array of capabilities to protect the organization, including those powered by both human intelligence and supplemental technologies.

EDR VS MDR VS XDR
Cyberattacks have become more common, more advanced and more costly, which is driving
the need for a comprehensive cybersecurity strategy. Central to every security strategy is a detection and response capability which catches threats that have circumvented traditional security measures. Here we explore three main detection and response tools:
Endpoint Detection and Response (EDR)
Managed Detection and Response (MDR)
Extended Detection and Response (XDR)

What is endpoint security?
Endpoint security solutions protect endpoints such as mobile devices, desktops, laptops, and even medical and IoT devices. Endpoints are a popular attack vector, and the goal of an attacker is to not only compromise the endpoint but also to gain access to the network and the valuable assets within.
Types of endpoint security
Attackers stay up to date on security trends in order to create stealthier attacks, rendering legacy antivirus obsolete. Endpoint security combines the preventive protection of an EPP solution as well as the detection and investigative features of an EDR.

Endpoint Protection vs. Antivirus: What Is the Difference?
Antivirus software helps businesses detect, eliminate, and prevent malware from infecting devices. Antivirus solutions are installed directly on endpoint devices, such as laptops, PCs, network servers, and mobile devices. These solutions detect malware by scanning files and directories to discover patterns that match the definitions and signatures of a virus. They can also only recognize known threats and must be updated to detect the latest malware strains.
Endpoint security threat prevention is fundamentally different from the approach of antivirus software. Instead of protecting an individual device, endpoint security solutions protect the entire business network, including all of the endpoints connecting to it.
There are several significant differences between endpoint protection and antivirus software. These include:
- Device coverage
- Protection from threats
- Continuous protection
- Advanced internal protection
- Admin control
- Enterprise-wide control
- Integration

What is the difference between NGAV and XDR?
NGAV is a combination of AI and machine learning with an emphasis on prevention. It’s able to protect against file-less attacks, unlike legacy antivirus.
XDR is an advancement of EDR that is designed to assess information outside of individual endpoints. If an attack were to get past NGAV and you don’t have XDR as an added safety measure, your systems become vulnerable to attack. NGAV is great for endpoint security, but it doesn’t easily work across multiple endpoints. This is where XDR steps in, as it has a greater scope.

EDRをさらに進化したXDRとは？エンドポイント対策の最前線
ランサムウェア対策の最前線で注目を集めるXDRとは何か
そこで近年では、EDR（Endpoint Detection & Response：エンドポイント検知・対処）製品を導入して、従来行ってきたネットワークセキュリティに代わる保護機能をエンドポイントで実行していくことが求められています。現実的には、完全なテレワーク下で脅威に対抗していくためには、EDRしか手だてがないとさえ言われています。
しかし、EDRにも課題があります。それは検知した脅威情報をどう管理し、どう対処していくかなど運用負担が大きいということです。世の中に存在する多くのEDRは、単に導入するだけでは脅威検知の部分しか実現できず、発生したインシデントへの対応や脅威ハンティングの部分は、人手に頼らざるを得ないのが実情です。そもそもEDRの運用では脅威情報に関する大量のアラートが通知されるため、その対処だけでもままならないという状況があります。
そうした中で、従来のEDRの課題を解消するべく同ソリューションをさらに進化させたコンセプトが 「XDR（eXtended Detection & Response）」 です。SentinelOne Japanのセールスエンジニアの富田隆一氏は「XDRという言葉にはさまざまな定義があり、理解のされ方も異なります。XDRが何でありどのように脅威を対処するのかを正しく把握することが重要になってきます」と強調します。
XDRの目標は「攻撃者のTTPsを検知し、素早く封じ込めること」
富田氏によると、XDRの目標は「攻撃者のTTPsを検知し、素早く封じ込めること」にあるといいます。
TTPsとはTactics Techniques & Proceduresの略であり、その訳の通り、いかに攻撃者の戦略・技術・手順を検知できるかがカギとなります。

EPP vs EDR: Which Should You Choose?
Why Choose EDR?
Endpoint detection and response provides intelligent detection and visibility. Experienced staff can filter false positives, find actionable data, and detect threats early. Most importantly, EDR makes it possible to respond to attacks on endpoints if other security measures fail.
Why Choose EPP?
EPP performs monitoring and threat detection provides monitoring and protection for endpoints. It requires little oversight and is easily managed by a qualified IT team. Unlike EDR, it does not require regular monitoring. If hosted in the cloud, it uses fewer resources and can be accessed from anywhere.
Endpoints are one of the most important assets for enterprises to monitor security threats. While EPP is reactive and designed to prevent attacks from common threat sources, EDR lets your organization respond faster and empowers security teams to take action and contain or stop the threat.
A combination of both EPP and EDR is best for most enterprise organizations. Many EPPs recognize this, by including an EDR feature as part of their platform. The best solution for your organization will depend on factors such as vulnerability, budget, and tolerance to risk for specific endpoints and the network at large.
